How much of a 70% orange juice drink must be mixed with 5 gallons of 10% orange juice drink to obtain a mixture that is 50% orange juice?
Answer provided by our tutors
let 'x' represent the amount of 70% juice that is added, then 'x+5' represents the total amount of juice:
0.50(x+5) = 0.70x + 0.10(5)
solving for 'x' we have x=10
10 gallons of 70% orange juice must be added
