Question 29021: Adult tickets for a play cost $15 and child tickets cost $1. If there were 29 people at a performance and the theater collected $155 from ticket sales, how many adults and how many children attended the play? Answer by Nate(3500) (Show Source):
You can put this solution on YOUR website! lets define the variables:
a=adult tickets c=children tickets
the two equations are:
15a+c=155
a+c=29
after combining them, you get a=9....plug in the "a" into one of the equations and you get c=20
9 adult tickets
20 children tickets
