Question 158963
A pineapple drink contains 15% pineapplejuice. how much pure pineapple juice should be added to 8 quarts of the drink to obtain a mixture containing 50% pineapple juice?
.
Let x = amount of pure pineapple juice added
.
"amt of pure juice" + "original amt of juice" = "amt of juice in final mix"
x + .15(8) = .50(8+x)
x + 1.2 = 4
.50x + 1.2 = 4
.50x = 2.8
x = 2.8/.50
x = 5.6 quarts
