Question

Oceanside bike rental shop charges 17 dollars plus 9 dollars an hour for renting a bike. Sara paid 53 dollars to rent a bike how many hours did she pay to have the bike checked out

Answer 1

Sara paid for 4 hours to have the bike checked out

Solution:

Oceanside bike rental shop charges 17 dollars plus 9 dollars an hour for renting a bike

Let "x" be the number of hours rented

Then, total cost is 17 dollars plus 9 dollars for "x" hours

Thus, we frame a equation as:

Total cost = 17 + 9(number of years)

Total cost = 17 + 9x

Sara paid 53 dollars to rent a bike

Therefore, total cost = 53

$53 = 17+9x\\\\9x = 53-17\\\\9x = 36\\\\x = 4$

Thus sara paid for 4 hours to have the bike checked out
