Answer:

Step-by-step explanation:

Let c represent the number of child tickets sold. Then 2c-14 is the number of adult tickets sold, and total revenue is ...

5c +8(2c-14) = 728

21c -112 = 728 . . . . . . simplify

21c = 840 . . . . . . . . . . add 112

c = 40 . . . . . . . . . . . . . divide by 21

2c-14 = 66 . . . . . . . . . number of adult tickets sold

66 adult tickets and 40 child tickets were sold.
