Question

Oceanside bike rental shop charges $12 (base price) plus $9 an hour for renting a bike. Melanie paid $93 dollars to rent a bike. How many hours did she pay to have the bike checked out

Answer 1

Answer:

An equation would look something like 14+9a=86

$14 initial fee plus $9 per hour for a total of $86

So subtract 14 from each side of the equation to leave you 9a=72

Divide each side by 9, leaving x=8

8 hours
