Question

Tickets to a carnival are $5 for adults and $3 for children. If 215 people attended and receipts were $925, how many tickets were bought for children?

Answer 1

5a + 3c = 925

a + c = 215

3a +3c = 645

2a = 925-645= 280

a = 300/2 = 140 adults

c =215-140 = 75 children

5(140)+3(75) =700+225= 925
