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? Let's answer step by step:
The number of tickets needed for the rollercoaster is 3 rides × 4 tickets / ride = 12 tickets. The number of tickets needed for the Catapult is 2 rides × 4 tickets / ride = 8 tickets. The number of tickets needed for the Ferris wheel is 1 ride × 1 ticket / ride = 1 ticket. Turner needs 12 tickets + 8 tickets + 1 tickets = 21 tickets. The answer: 21.
