One canned juice drink is 25% orange juice; another is 10% orange juice. How many liters of each should be mixed together in order to get 15L that is 125 orange juice?

Answer 1

use x L of 25% and 15-x of the 10%

(you have a typo at the end, I will assume you meant 12 %. If this is not right, then change the value on the right side of the equation below)

then

.25x + .1(15-x) = .12(15)

solve for x

Answer 2
