Question

Oceanside Bike Rental Shop charges 18 dollars plus 6 dollars an hour for renting a bike. Mary paid 66 dollars to rent a bike. How many hours did she pay to have the bike checked out? Write an equation then solve.

​

Answer 1

Explanation:

Let x be the hours Mary rented the bike. Her total cost would be the sum of the $16 up-front service charge plus x (hours) times $6/hour, to account for the rental time. We can write that as:

$16 +( $6/hr.)x = $66

16 + 6x = 66

6x = 50

x = (50/6) hours

x = (25/3) hours

x = 8 1/3 hours
