Question

A movie theater sells tickets for $12 for adults and $7 for children.

On one weekend, 267 people visited and the total ticket sales was $2379


How many adults attended?

Answer 1

102 adults, 165 children

Explanation:

Let a be the number of adults, and let c be the number of children. We set up and solve this system of equations:

a + c = 267---------> 7a + 7c = 1869

12a + 7c = 2379------->12a + 7c = 2379

-----------------------

5a = 510

a = 102, c = 165
