Answer:
42 general admission tickets and 57 youth tickets were sold.
Explanation:
Since the ice rink sold 99 tickets for the afternoon session, for a total of $ 915, and general admission tickets cost $ 15 and youth tickets cost $ 5 each, to determine how many of each kind of tickets were sold the following calculation must be performed:
15 - 5 = 10
99 x 5 = 495
915 - 495 = 420
420/10 = 42
99 - 42 = 57
(42 x 15) + (57 x 5) = X
630 + 285 = X
915 = X
Thus, 42 general admission tickets and 57 youth tickets were sold.
