Hey
I want to replace oil
Volume = 1500ml
I can just get 250ml out at once then i have to refill it with fresh oil... the oil mixes 100%
So:
Step 1:
1500 old oil -> 250 ml out and 250ml fresh in
Step 2:
1250 old oil 250ml fresh oil
When i let 250ml out and refill with fresh oil:
1040 old oil 460ml new oil....
So how many times i have to repeat that to get 95% new oil ??
>>
hang on op
imma try to work it out

u have to solve

find n by taking logs

umm solve for x
not n
that was a typo
