Problema Solution
One canned juice drink is 25% orange juice and another is 5% orange juice. How many liters of each should be mixed together to get 20 liters that is 8% orange juice?
Answer provided by our tutors
let
x = liters of the 25% orange juice
y = liters of the 5% orange juice
x and y mixed give 20 liters of 8% orange juice
x + y =20
0.25*x + 0.05y = 0.08*20
by solving the system of equations
x + y =20
0.25*x + 0.05y = 1.6
we find
x = 3 liters
y = 17 liters
