Question

Answer 1

Explanation:

Answer:

10 liters of orange juice

5 liters of champagne

Explanation:

Let c represent the number of liters of champagne Lauren uses. Then (15-c) will be the number of liters of orange juice. The total cost of the mix will be ...

12c +1.50(15-c) = 5.00(15)

10.5c = 52.50 . . . . . subtract 22.50, simplify

52.50/10.5 = c = 5 . . . . divide by the coefficient of c

Then the amount of orange juice is ...

15 -c = 15 -5 = 10 . . . . liters

Lauren should use 5 liters of champagne and 10 liters of orange juice.
