Question 1102865
Mix a solution that is 30% alcohol with a solution that is 80% alcohol to make 625 mL of a solution that is 60% alcohol.
 How much of each solution should you use? 
:
let x = amt of 80% solution
we know the total amt will be 625, therefore
(625-x) = amt of 30% solution
:
the equation
.80x + .30(625-x) = .60(625)
