An advertisement for a pineapple drink claims taht the drink contains 15%pineapple juice. How much pure pineapple juice would have to be added to 8 quarts of the drink to obtain a mixture containing 50% pineapple juice?

This is a mixture problem.

Pineapple drink + pure juice = mixture
8(.15) + x = .50(8 + x)

Solve for x.
