Question

For a ride on a rental scooter, Henry paid a $7 fee to start the scooter plus 7 cents per minute of the ride. The total bill for Henry's ride was $17.01 . For how many minutes did Henry ride the scooter?

Answer 1

Given data:

$7.00 for start the scooter

$0.07 per minute

Total bill: $17.01

1. Subtract from the total bill the fee to start the scooter:

`17.01-7.00=10.01`

$10.01 is the cost per all the minutes Henry ride.

2. Divide the cost per all the minutes into the cost per minute:

`(10.01)/(0.07)*(100)/(100)=(1001)/(7)`

Then, Henry rides the scooter for 143 minutes
