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.

  • Algebra -

    C=23-A
    9A+8(23-A)=193
    9A+184-8A=193
    184+A=193
    A=9

    C=23-A
    C=23-9
    C=14

    14 Children attended the play
