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

Answer:

  Adult:  50

  Child:  110

Step-by-step 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
