Adult tickets for a school fashion show cost $8 and student tickets cost $5. The total receipts for 200 tickets are $1150. Using elimination method, determine the number of each ticket that was sold

Answer 1

a = adult tickets

s = student tickets

( a + s = 200 ) (-5) ..... -5a - 5s = -1000

8a + 5s = 1150 ..... + 8a + 5s = 1150

3a = 150

a = 50

plug into original equation

50 + s = 200

s = 150

a = 50 and s = 150
