One canned juice drink is 15% orange juice; another is 10% orange juice. How many liters of each should be mixed together in order to get 5L that is 11% orange juice?
How many liters of the 15% orange juice should be in the mixture__ L ?
How many liters of the 10% orange juice should be in the mixture__ L ?

volume of 15% OJ  x L
volume of 10% OH  5x L
.15x + .1(5x) = .11(5)
times 100 , don't like them decimals!
15x + 10(5x) = 55
15x + 50  10x = 55
5x = 5
x = 1
So 1 L of the 15% stuff and
4 L of the 10% stuff
