For the school play, one adult ticket costs $5.00 and one student ticket costs $3.00. Twice as many student tickets as adult tickets were sold. The total receipts were $1650. How many of each kind of ticket were sold? Solution Given this problem, Let adult ticket be x , and student ticket be y Then, it\'s 5x+3y = 1650 and since it said twice as any student tickets as adult tickets were sold, it will be y = 2x With 5x + 3y = 1650 and y = 2x 5x+3(2x) = 1650, 11x = 1650, x = 150 tickets y = 300 tickets so adult tickets : 150, student tickets : 300 tickets.
