one canned juice drink is 15% orange juice; another is 5% orange juice. how many liters of each should be mixed together in order to get 10L that is 9% orange juice?

x liters of .15 oj
then (10x) of .05 oj
amount of oj in final = .15 x + .05(10x)
= .09 *10 = .9
so
.15 x +.5  .05x = .9
.1 x = .4
x = 4 liters of .15
then
6 liters of .05
