For a ride on a rental scooter, Joe paid a $7 fee to start the scooter plus 7 cents per minute of the ride. The total bill for Joe's ride was $20.16. For how many minutes did Joe ride the scooter?

Answer 1

Let $x$ be the number of minutes Joe rode the scooter.

Joe paid a $7 fee to start the scooter plus 7 cents per minute of the ride. So the total cost of the ride is $0.07x + $7.

Since the total bill for Joe's ride was $20.16, we can set up the equation:

$0.07x + $7 = $20.16

Subtract $7 from both sides:

$0.07x = $13.16

Divide by $0.07 on both sides:

$x = \frac{13.16}{0.07} = 188

Joe rode the scooter for 188 minutes.
