How many liters of the 20% orange juice should be in the mixture?

How many liters of the 5% orange juice should be in the mixture?

Answer provided by our tutors

let 'x' represent the liters of 20% juice, then '15-x' represents the liters of 5% juice


0.10(15) = 0.20x + 0.05(15-x)

solving for 'x' we have x=5


15-5=10


5 liters of 20% juice should be mixed with 10 liters of 5% juice
