Adult tickets for a play cost $9 and child tickets cost $8. If there were 23 people at a performance and the theater collected $193 from ticket sales, how many children attended the play?

A = number of adults

C = number of children

Set up two equations.

A + C = 23

9A + 8C = 193

Solve the equations simultaneously to find A and C.
