Solution
(a) To find out how many hours of bike use a customer gets per dollar, you need to divide the total hours by the total cost.
So, 7 hours / $32 = 0.21875 hours per dollar.
If we round this to the nearest hundredth, it would be 0.22 hours per dollar.
(b) To find out how many minutes Amanda takes per mile, you need to divide the total minutes by the total miles.
So, 58 minutes / 7 miles = 8.28571429 minutes per mile.
If we round this to the nearest hundredth, it would be 8.29 minutes per mile.
