The Reel Good Cinema is conducting a mathematical study. In its theater, there are 200 seats. Adult tickets cost $12.50 and child tickets cost $6.25. The cinema’s goal is to sell at least $1500 worth of tickets for the theater. Write a system of inequalities that can be used to find the possible combinations of adult tickets, x, and child tickets, y, that would satisfy the cinema’s goals.
y+x=200
