A bicycle rental company charges $12 for the first hour and $5.75 for each additional hour. Determine the maximum number of hours you can rent a bike if you only have $81.

Answer 1

Let x = the number of hours you rent the bike. Your cost is:

Cost=$12+$5.75x

If you only can afford a cost of $81:

$81 = $12+$5.75x

$69 = $5.75x

Solve for x.
