Question

For a ride on a rental scooter, Chau paid an $8 fee to start the scooter plus 6 cents per minute of the ride. The total bill for Chau's ride was S12.14. For how
many minutes did Chau ride the scooter?

Answer 1

Chau rode the scooter for 69 minutes.

Given that :

Initial fee paid = $8

Fee per minute = 6 cents = 6/100 = $0.06

Hence,

Total ride cost = $8 + (fee per minute × number of Minutes)

If total Cost of ride = $12.14

Let number of minutes = m

Hence, we have :

12.14 = 8 + 0.06m

12.14 - 8 = 0.06m

4.14 = 0.06m

m = 4.14 / 0.06

m = 69

Hence, he rode the scooter for 69 minutes
