Question

The movie theater took in $1220 one Monday night. The number of $7 childs tickets was ten more than twice the number of $9 adult tickets. How many of each were sold?

Answer 1

Adult: 50

Child: 110

Explanation:

Adult: x

Child: 2x + 10

7(2x + 10) + 9x = 1220

14x + 70 + 9x = 1220

23x + 70 = 1220

23x = 1150

x = 50

Adult: 50

Child: 2(50) + 10 = 110
