Step-by-step explanation:

Let u represent the amount (ounces) of cherry drink. Then the amount of cola is (10-u). The total cost of the cherry cola drink is ...

  0.50(10 -u) +1.70u = 1.34(10)

  1.20u +5 = 13.40 . . . . . . simplify

  1.20u = 8.40 . . . . . . . . subtract 5

  u = 7 . . . . . . . . . . . . . divide by 1.20

The amount of cherry drink was 7 ounces.

The amount of cola drink was 3 ounces.
