Question

A bike rental company charges $12 rental fee plus $6 per hour . Alyssa paid $54 to rent a bike . How many hours did she rent it ?

Answer 1

7 hours

Explanation:

This problem can be written into the equation y=6x+12 because the rental company charges six dollars per HOUR (or x) added with the $12 rental fee (the 12). The y would be considered 54 since that would be what 6x+12 will eventually equal out to, so the equation would now look like 54=6x+12. Now you must isolate the variable in order to solve for x. Subtract 12 on both sides and this will leave you with the equation 42=6x. Now divide 6 on both sides and that will leave you with x=7 meaning she rented the bike for 7 hours.

Answer 2

7 hours im pretty sure.
