Final answer:
The unit rate per ride at the amusement park is calculated by dividing the total cost ($7.50) by the number of rides (3), resulting in a unit rate of $2.50 per ride.
Step-by-step explanation:
The unit rate per ride at the amusement park can be calculated by dividing the total cost by the number of rides. If it costs $7.50 for 3 rides, then the unit rate is found as follows:
- Divide the total cost by the number of rides. Total cost: $7.50; Number of rides: 3.
- $7.50 ÷ 3 = $2.50 per ride.
Therefore, the unit rate is $2.50 per ride.
