The prices of tickets for the local rock concert were $16 for Friday night and $28 for Saturday night. The total attendance for the two nights was 1090. If the total receipts were $24,232, how many people attended Saturday night?
Let x: number of tickets that sold on Friday, y: number of tickets that sold on Saturday night
16x+28y=24232 x+y=1090 x=1090-y, so 16(1090-y)+28y=24232 17440-16y+28y=24232 12y=6792 y=566. As a result, there will be 566 tickets sold on Saturday night. Hope it help!
