Question 399944: I understand what the question is asking me. My problem is I do not know how to set it up to solve it. If I could just figure out how it write the formula I could probably solve it. It goes as follows:
How much 2% alcohol must be mixed with 10% alcohol to get 2000 ml of 8% alcohol?
Answer by josmiceli(19441) (Show Source): You can put this solution on YOUR website!
Let = ml of 2% alcohol needed
Let = ml of 10% alcohol needed
It follows, then:
= ml of alcohol in 2% solution
= ml of alcohol in 10% solution
In words:
(ml of alcohol in final solution)/(ml of solution) = 8%
----------------
(1)
(2)
----------------
(1)
(1)
Multiply both sides of (2) by
and subtract (2) from (1)
(1)
(2)

ml
And,

ml
500 ml of 2% alcohol are needed
1500 ml of 10% alcohol are needed
-------------------------
check answer:
(1)
