Oceanside bike rental shop charges 13 dollars plus 9 dollars an
hour for renting a bike. mike paid 67 dollars to rent a bike. how many
hours did he pay to have the bike checked out?

he paid for 6 hours to have the bike checked out.

Step-by-step explanation:

Oceanside Bike Rental Shop charges 13 dollars plus 9 dollars an

hour for renting a bike. Let x represent the number of hours that a person rents the bike. The total amount paid for renting the bike for x hours would be

13 + 9x

Mike paid 67 dollars to rent a bike. This means that

13 + 9x = 67

Subtracting 13 from both sides of the equation, it becomes

9x = 67 - 13 = 54

x = 54/9 = 6
