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
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.
