Turner wants to ride the rollercoaster 3 times, the Catapult 2 times and the Ferris wheel once. It costs 4 tickets to ride the rollercoaster, 4 tickets to ride the Catapult and 1 ticket to ride the Ferris wheel. How many tickets does Turner need?
The number of tickets needed for the rollercoaster is 3 rides × 4 tickets/ride = <<3*4=12>>12 tickets.
The number of tickets needed for the Catapult is 2 rides × 4 tickets/ride = <<2*4=8>>8 tickets.
The number of tickets needed for the Ferris wheel is 1 ride × 1 ticket/ride = <<1*1=1>>1 ticket.
Turner needs 12 tickets + 8 tickets + 1 tickets = <<12+8+1=21>>21 tickets.
