Problema Solution
One canned juice drink is 30% orange juice; another is 10% orange juice. How many liters of each should be mixed together in order to get 20L that is 23% orange juice?
Answer provided by our tutors
let
x = L of the 30% orange juice
y = L of the 10% orange juice
the new mix is 20L thus
x + y = 20
the new mix contains 23% orange juice
0.30x + 0.10y = 0.23*20
by solving the system of equations
x + y = 20
0.30x + 0.10y = 0.23*20
we find
x = 13 L
y = 7 L
