Again please NO answers! Only on how to solve. One canned juice drink is 20% orange juice; another is 5% orange juice. How many liters of each should be mixed together in order to get 15L that is 14% orange juice?

.2 x + .05 y = .14 (x+y) and x+y = 15

O.J.=(0.14)(15)=2.1 lit ers. 1. 0.2X+0.05Y=2.1 2. X + Y = 15 To solve by elimination,multiply both sides of equation 1 by(-)5: -X-o.25Y=-10.5 X + Y = 15 Y = 6 liters @ 5% O.J. X = 9 liters @ 20 % O.J.
