Question

1. A movie theater sells tickets for $9.00 each. Senior citizens receive a discount of $3.00. One evening the theater

sold 636 tickets and took in $4974 in revenue. How many tickets were sold to senior citizens?

Answer 1

250

Explanation:

x is adult tix, y is senior tix

9x + 6y = $4974

x+y= 636

x=636-y

9(636-y) +6y = 4974

5724 - 9y + 6y = 4974

-3y = 4974-5724

-3y=-750

y=250
