To determine how many times the young can ride the rollercoaster, we'll start with the total number of tickets and subtract the tickets used for the carousel, then divide the remaining tickets by the number of tickets required for each ride on the rollercoaster.
- Total tickets: 37
- Tickets used for carousel: 4
- Tickets remaining after carousel: \[ 37 - 4 = 33 \]
- Tickets needed for each rollercoaster ride: 3
Now, we will divide the remaining tickets by the number of tickets per rollercoaster ride to find out how many times he can ride the rollercoaster: \[ \text{Number of rides} = \frac{33}{3} = 11 \]
Therefore, he can ride the rollercoaster 11 times.
