Answer:
- 40 adult tickets
- 28 children's tickets
Step-by-step explanation:
Let "a" represent the number of adult tickets sold. (We like to let the variable represent the higher-value item.)
Total sales was then ...
11a +6(68-a) = 608
5a + 408 = 608 . . . . . eliminate parentheses
5a = 200 . . . . . . . . . . .subtract 408
a = 40 . . . . . . . . . . . . . divide by 5
40 adult tickets were sold, and 28 children's tickets were sold.
