First we need to know the game's price. It only says that it costs $1 plus its price, not that the game's price is $1.

>>37670465
Is this impossible?

game = $1
half it's price = .50
new game price = $1.50
This repeats forever

1+(1/2) = 1.50

All other answers are retarded.

No right answer because the meaning if "its price" is ambiguous. Depending on how it's defined, the game will cost either $1.50 or $2

>>37670747

shut the fuck up you little shit REEEEEEEE

>>37670465
Undefined, you can't just assume that the original cost of the game is also one dollar

>>37670465
wrong its

>>37670717
LMAO
True answer is infinite, since it's stuck in a loop of adding half it's price to it.

>>37670753
If "its price" means the original price, i.e. $1, then half of that is 50 cents, so the price of the game is $1.50

But if "its price" is defined as the final price, then

$1 + p/2 = p

Therefore, in this case the price is two dollars.

Glad I went law and make more in a quarter than a MSc in Math makes in a year. Stay BTFO.

>>37671277
That's why we use x as a variable. Since we do not know it's original price. Although the problem with the question is it's vagueness so there's no true answer per se. If we interpret it as "a game is marked up and now costs it's 1 dollar plus half it's price" and then that answer is 2.

A game costs $1 plus half it's price.
How much does it cost?
First one is not even gramatically correct.

it should be
>A game costs $1 plus half its price.
Assuming above is the correct version:
game -> cost = ($1 + 0.5price)
invalid.
Reason: two unknowns
price != cost
The answer would not be a real number.

Let's make this solvable instead
>A game costs $1 plus half its "cost"
Now we're talkin':
game -> cost = ($1 + 0.5cost)
game -> cost = ($1 + 0.5cost)
game -> cost/0.5 = ($1 + 0.5cost)/0.5
game -> 2cost = ($.05 + cost)
game -> cost = ($.05 + cost)/2
cost = infinite [fucking ascii not allowed, noob robot]
'plus half itself' ads indefinitely and infintely and it is not stated when the statement would halt/end.

Conclusion:
Reconstruct the problem, faggot.

Infinite.

1/2=0.5
1+0.5=1.5

But then the price is 1.5 so we have to half that and add it again so

1.5+0.75=2.25

But then the price is 2.25 so we have to half that and add it again...

The price isn't a goddamn equation. No one labels that the price of their apple is "1 + apple price." The game doesn't cost 1 dollar but also a bit more. Literally no one who was taught in any English speaking country would interpret it as that. If you see that an item has a 50% discount, do you go up to the cashier and say it is actually an infinitely small number because it kept discounting itself?

The equation is simply what was INCLUDED in the price. 1 + half its price. 1 + (0.5x) = x. x can only be 2.

Is it the cost? If so, you have just created recursion.

To my fellow brainlets who, like I, failed to see the logical connection at first

If X = 1/2X + (?), what ever (?) is MUST also be half of X. You have to add a half to a half to make a whole

>>37674080
People are interpreting the problem as "A game costs $1, now add half its cost(which has already been established as $1)."

>>37674190
If half the price of the game is added to 1, 1 would also have to be half to make up the rest of the original price.

You need to add 50% to 50% to get 100%

>>37674238
And that interpretation might make sense if you were working for a store or something, and you wanted to raise the price of a game from $1 to $1.50. Then the (new) price of the game is equal to $1 plus half of its (old) price.

Although I think the most logical interpretation is that the game costs $2

>>37674190
On this off chance that you're not trying to troll me, I'll explain it as clearly as it possibly can be. Any further argument after this explanation is guaranteed to be bait so I'm not going to bother replying.
There are two values in the equation. One of them is an unknown amount which is worth 50% of the total.
Since there is only one other value in this equation, this must make up the remainder of the total, in other words this is the remaining 50% not accounted for. And we know this is $1 because it's given in the question. So multiply it by two to make it 100% and you have the full price.
>>37674238
There is NO WAY to interpret the question this way unless you have no understanding of English, mathematics, and logic, all at the same time.

>>37670465
>Price is the amount a customer pays for that product or service. The difference between the price that is paid and the cost that is incurred is the profit the business makes when the item sells.

Without knowing the price, you can't determine the cost in this case.

No in this context the price is the same thing as the cost.

>no understanding of English

Well the OP fucked up something as simple as it's and its.

>>37674454
>in this context
what fucking context? is just an image with text. Price and cost are different things, this is basic economy knowledge.
You have 2 variables (C: Cost and P: Price) and only one equation that relates them
C = $1 + P/2

There are infinite solutions to this equation. This is basic math knowledge. So congratulations on failing at both economy and math

Lets break down the three lines of logic in this thread; one of which has no respect to logic, another which makes no sense grammatically, and the last which is perfectly feasible

1) The game initially costs 1 dollar and then for some reason also costs half of the final price. Therefore, the game costs 1.50 but then the statement is false for the game did not cost 1 creating a recursion. One could come to this conclusion with the following:

>A game costs $1. Add half of its final price to its initial price. How much did it initially cost?

2) The game initially costs 1 dollar and half of its final price. While this could be a reasonable thing to interpret, the sentence establishes that the cost is more than 1 dollar and therefore the initial price was not 1 dollar. One could come to this conclusion with the following:

>A game costs $1. Add half of its initial price to its final price. How much does it cost?

Both of these lines of logic assume that the price is itself an equation and we are determining a new price after having known an initial price.

3) The game's cost is included in the equation. The game costs 1 + half of its (full) price. x = 1 + 0.5x and x therefore can only be 2. There is nothing logically incorrect with this line of reasoning.

>A game costs $1 plus half of its price. How much does it cost?

This one makes the most sense considering the grammatical implication that the game already costs something and we are not pricing it and it requires no change to the question to be understood clearly.

>>37674576
Cost is just the verb form of price (noun). Don't be so retarded, this question isn't about English semantics and it's extremely obvious what it means.

>>37674530
I can't figure out which ball it is with two weighs, but I can tell how to determine whether it's lighter or heavier than the other 7 balls.

First compare the weight of any four balls with the weight of the other four balls. Now take the four balls that were lighter than the other four. Now conpare the weight of two of those balls with the other two.

If they have the same weight, then that means the ball with a different weight was in the first four balls that were heavier than the other four, which means that the odd ball is heavier. On the other hand, if the the pairs of balls have different weights, then one of those four balls most be the odd ball, thus the odd ball is lighter than the other 7 balls.

I'm a brainlet so sorry if that was incoherent.

Also, this isn't a mathematics problem, it's a grammar one. If you wrote this as an equation there would be no question. If you wrote the sentence unequivocally there would be no confusion at all either : "If half the price of the game equals 1$, how much does it cost?"

Left: $1.50

Those calling for an infinite loop are talking about compound interest:

which makes little sense given the context.

>>37675110
How would you word the question to avoid ambiguity?

>>37671144

Damn you're smart Anon, so damn smart.

Doesnt it depend on how you interpret the question? A game costs (price) 1, plus half its price. 1.50

A game costs, 1 plus half of the price. 2.
You can attach the price as set to 1 or as defined by 1+1/2x. Idk

I think 2 is the intended right answer tho

>I got BTFO by elementary algebra but I don't even need it so lmao

>>37675348
Of course not. If it costs 1, it costs 1. "Half the price" implies 1 is not the cost.
"x plus y" makes it obvious that x is not the price. X can't be X plus Y if Y>0, as it is in this case.
Those are just big words for "if you thought 1 was the price you can't read".

>>37670465
If it's not 1.50 then I don't give a shit, (((math))) like this would never apply in the real world.

>>37670465
$infinite I guess since it's contantly half added 1+.5=1.5 then 1.5 is the price so 1.5+.75= 2.25 and so on.

>>37670573
No it's 2 because was being added is growing exponentially. Additionally x can't equal half itself plus one you idiot your math is stupid.

I was just responding to the second sentence.
let x = 2
"half of x" is "half of 2" which equals 1.
"half of x" plus 1 = 1+1 = 2 = x
What do you mean (x) and 1 are clearly separate parts?

>>37670465

$1 has to be half it's price since for 1/2x + y = x, y also must be 1/2x

1 + 1 = $2

None of this infinite recursive shit lel

>>37676214
many people ITT thought 1 was the price (x) and thought "half its price" meant "half of 1" so they answered 1.5

2 dollars. Its a classic converging series, 1/2^n, starting at n=0 and going to infinity.

>>37670465
1+.5x=x
-.5x from both sides
1= .5x
Divide by .5 on each side

The answer is something about the difference between price and cost. Don't remember the details.

>>37671824

It's not a convergent series because the price/2 gets added to the price and increases itself each iteration. Take a look:

Price a. is $1
Price b. is $1.50 ($.50 increase)
Price c.is $2.25 ($.75 increase)
Price d.is $3.38 ($1.13 increase)

>>37676631
>>37676631
It really doesn't, because such variables don't exist until specifically stated. If they were a factor, the problem would give you a percentage of benefit somewhere.
Stop trying to make the problem more complex than it is. You're stuck in a problem of semantics just because the pic didn't use the most adequate word.

Are you sure about that? Quote the part where it says so.

If you read it as "the price is 1" then you're not reading the half part. The only option is to read it as "the price is (1 + half of the price)".

The equation is wrong. You should have typed "its" instead of "it's". Having wrong syntax is like dividing by zero.

Cost of game: x.

2(X-1) = 2 * X/2

2X - X = 2

Cost = one plus half of price
Price = unspecified

c=1+(0.5*p)
p=?

Theory 1: p = initial game cost, which is 1
c=1+(0.5*p), p = 1
>1*0.5=0.5
>1+0.5=1.50
c = $1.50

Theory 2: p=c, c=1+(c*0.5)
>c=1+(1+(c*0.5)*0.5)
>c=1+(1+(1+(c*0.5)*0.5)*0.5)
>c=1+(1+(1+(1+(c*0.5)*0.5)*0.5)*0.5)
>ad infinitum (unsolvable)
c = ?

Theory 3: we don't know p because not enough information is given
>unsolvable

Thus I would conclude that $1.50 is the most reasonable answer, although it is impossible to know if it is the correct answer.

It means that its price, which we will call X, is equal to 1 + X/2.

Then solve the equation X = 1 + X/2 using 5th grade Algebra, to get X = 2.

And indeed, 1 dollar plus half of two dollars is equal to 2 dollars.

$1.50, assuming I purchase it once. The question is somewhat misleading in that it's a series that converges to a singular point, such that;

Un = 1 + (U_{n-1}/2)

Which results in a Geometric Progression, we can find the limit of Un as n tends to infinity,

U_inf = a / 1 - r
a = 1, r = 0.5,
1 / (1 - 0.5) = 2

The answer is $1.50 - or $2, depending on how one approaches the question. I place bets on $1.50 since no store would be as autistic as to charge you over and over.

Because $1 is half of $1

>>37670465
If you get $1.50 you cannot read properly.

>"A game costs $1 plus half its price"

=> "The price is $1 plus another half of price"

(price) = $1 + (price / 2)
2(price) = $2 + price
price = $2

If you get $1.50 you have read "The price of a game is $1. What is the price plus another half?" Which is not what was asked.

$2.

Anything else is wrong.

Ahh, I get it now. The question is literally giving you the answer as to how much you should add. Half of 1.50 is 75 and that can't be the answer because the question is saying that the game cost is 1 dollar PLUS half its price. Add another 1 and you get 2 dollars. I feel dumb for not knowing this before.

He did not write gc on both sides. Copy and paste what you're referring to?

>>37670465
This is impossible to solve, as this question is self-recursive.

Let x be game price

x + x(.5)

>>37670465
>a game costs half its price
You don't need to write the dollar part to make your lazy paradox

>>37671144
You are the biggest, smartiest smarty pants on this whole board! Good job!

>>37683798
So the price is $1?

Then it says plus half of its price, meaning $.50

Why is that wrong

The sum is

x = x + (x/2)

If x is one, it is 1 + 0.5
If x is two, it is 2 + 1

no solution.

>>> "why is it not $1.50 hurrr"

because the game price is not $1

>>37670573
You're math is good. You can also implement an infinite geometric series. Yes, since the ratio is 1/2 (less than 1) you can find the total. We start with 1 since that's what we add in the beginning and it's ratio is 1/2
Sum = (a1 /( 1 - r))
= 2

People who solved it as x = x/2 + 1 aren't true math people.

>>37679896
You're so fucking stupid jesus christ. It's price is $1 plus half of its price. If its price is $2 then $1 plus half of $2 is $1+$1 = $2. This is THE MOST BASIC MATHS. I literally learnt this when I was 10.

>>37670850
You just added parentheses to an English problem.

1.50$.

The question is worded to be misread and it's half price, which would be 0.50$

That's why they used it's instead of the correct word, its

/thread

Wait, this is impossible to solve right? You have two variables, and you'd need at least two right?
1+0,5x=y is impossible to solve. Am I missing something?

Oh dear, this is a train wreck. For those of you who are answering this problem with math(s) first, let me explain. This is a question that needs to be broken down by objectifying verbs and subjects. A game >costs< [So we are seeing the original price of the subject, since it says costs, we are going to be told the value] 1$.

>Game Cost = 1$

Plus half it's price. It does not say half it's ORIGINAL price. That would indicate that the value of the game cost would be changed and you'd need to double the value, as the game was already reduced. So since it does not say >original< price, we can assume the half is from one dollar.

Half of 1$ is .50 cents.

The question ends there, so you have two values to add up. 1+.50 would be 1.50, there is no other part of the question remaining. Somehow, people learn Pemdas once and think they belong to Mensa, but if you can't simply identify an algebraic expression through a written question, you've already lost.

>Newfags

>>37687014
Yes, you are. If x is the price in your equation, and y is also the price, then you don't have two independent variables.

Price of game + half of price = price of game

The question is broken, and cannot be answered. a + 0,5a is not a.

>>37670526
>$2. Why are you even asking this question?

Because it's a classic ambiguous question. The answer is either $2 or $1.50 depending on how you interpret the question -- and both interpretations are equally reasonable.

It's a guaranteed troll question because it will get a lot of people arguing about the answer -- since only a tiny percentage of people have the ability to perceive both interpretations.

>>37687553
>The question is broken, and cannot be answered. a + 0,5a is not a.

It is if a = 0.

>>37687064
Wrong.
The problem is recursive and unsolvable.
>A game costs $1 plus half its price
That doesnt mean it starts at $1 plus $0.50, because then if you reread the question now it's $1 + $0.75, and so on for infinity.
Have you ever done algebra, you dumbshit?

>>37687702
>0 + 0,5 = 0

Original nigggggger post

>>37687741

How about doing it correctly, instead?

a + 0,5a = a [the assumption given in >>37687553 ]

0,5a = 0 [obtained by subtracting a from both sides]

a = 0 [obtained by dividing both sides by 0,5]

Hence we conclude that a = 0, as I correctly pointed out before.

The problem can be interpreted recursively, and is solvable.

It is possible to perform algebra with infinite expressions.

Pic shows how the infinitely-recursive interpretation can be solved to get the same answer as the non-recursive interpretation.

>>37687064
That's not a reasonable interpretation.

You've theorized two different variables, P (the price), and C (the cost), and you believe that they represent different things. You claim that P=1 and C=1.5.

However, if you read the original question carefully, you'll see that it doesn't support your interpretation.

The original question defines what C is, but it doesn't define what P is. Since P is undefined, we can't calculate C.

If you insist on making a distinction between P and C, then the best you can do is the following unsolvable equation:

C = 1 + P/2

which can't be solved because P was never defined.

If you think that the phrase "A game costs $1" is the definition of P -- notice that it uses the word "cost", not "price", so hence, it's a statement only about C, not P. The only way you can justify P=1, then, is to collapse P and C into the same variable. But collapsing P into C defeats your original idea of theorizing that P and C are independent variables -- turning your entire argument into an inconsistent mess.

>>37670465
If you are a semanticsfag, then the question cannot be answered because price and cost are different

If you don't care about semantics and price and cost are the same thing to you then the answer is $2

It's a paradox.

holy fuck now I feel like a brainlet.

I'm starting a math PhD program in the fall and this thread is triggering my autism hard ESPECIALLY those who get the right answer after using an infinite sum for no fucking reason

>>37689294
Do asymptotes trigger you? Enlighten us, Math Wizard.

>>37684328
It's a dumb question but cost =/= price.

Price is the value you'd find listed at the store. Cost is what you pay for the item.

The game costs 1$ plus half it's price. They're saying that = 2. It's wrong because they're saying it's total cost = 1 + 1/2(listed sales price). However that method is also wrong because the listed sales price is not determined and can be any number.

The question can't be solved.

>>37684328
>>37689439
The question can be solved though if you treat the initial "cost" as the listed sales price. Which would then be 1 + .5.

1.50$ would be how your general populace translates the problem so that's what people would pay anyways. Question is dumb.

>A game cost $1 plus half its price how much does it cost?

One dollar plus half its price.

Once you gain more mathematical maturity, you will understand that it's worthwhile and interesting to show that both infinite and finite techniques can be used to solve this problem, and that both yield the same answer.

Mathematics is all about studying patterns and developing tools to solve problems based on those patterns. If multiple tools can be used to solve a problem, then that indicates an underlying relationship between those tools -- and that relationship is itself worthwhile to study.
