Oceanside Bike Rental Shop charges a 14 dollar fixed fee plus 6 dollars an

hour for renting a bike. Keith paid 68 dollars to rent a bike. How many

hours did he pay to have the bike checked out?

9 hours

Step-by-step explanation:

Renting a bike costs $14 plus $6 per hour.

Keith paid $68

Hours paid for by Keith is therefore

$68 - $14

= $54

That's amount left after renting the bike.

Hours paid for = $54/6 since an hour costs $6

= 9

Keith paid for 9 hours

68 - 14 = 54, 54/6 = 9 hours
