Question

How many ounces of pure cranberry juice and how many ounces of a citrus fruit drink containing 14% fruit juice should be mixed to get 172 oz of a fruit drink that is 25% fruit juice?

Answer 1

Let cranberry juice be x.
Let citrus fruit juice be y.

x + y = 630
x + 0.1y = 630*0.23

Solving this yields,

x = 91
y = 539

Therefore, you need 91 oz of pure cranberry juice and 539 oz of fruit juice.
