Answer:
You can go on 7 rides.
Explanation:
I subtracted $15 from $58 which left me with $43 to go on rides. So every time you would go on a ride you would have to take away six. So I just subtracted $6 until I got down to a very small number.
Ride number 1: 43 - 6 = 37
Ride number 2: 37 - 6 = 31
Ride number 3: 31 - 6 = 25
Ride number 4: 25 - 6 = 19
Ride number 5: 19 - 6 = 13
Ride number 6: 13 - 6 = 7
Ride number 7: 7 - 6 = 1
