Answer:
7
Step-by-step explanation:
Admission cost = $15
Cost per ride = $3
Total amount spent = $36
We can obtain the number of rides thus :
Let number of rides = x
Admission cost + (cost per ride * number of rides) = total amount spent
15 + 3x = 36
3x = 36 - 15
3x = 21
x = 21 / 3
x = 7
Number of rides = 7
