One canned juice drink is 30% orange juice, another is 5% orange juice. How many liters of each should be mixed together I order to get 25L that is 28% orange juice?
Answer provided by our tutors
let
x = L of the 5% orange juice
y = L of the 30% orange juice
the mix is 25 L of 28% orange juice
x + y = 25
0.05x + 0.30y = 0.28*25
by solving the system we find
x = 2 L
y = 23 L
