Question

Marissa and haylie met for dinner in downtown Savannah. Marissa did flat-rate valet parking for $20. Haylie went to another valet and paid $5 up front and $2.50 for every hour, including the first hour. Ultimately the friends end up paying the same amount. How long did they stay? How much did each one pay?

Answer 1

6 hours; each paying $20

Explanation:

To start off, we know that Marissa paid exactly $20 for parking. Since we know that Marissa and Haylie paid the same amount, we must now move on to Haylie.

Haylie paid $5 upfront. Now we must figure out how many hours Haylie must have stayed if each hour costed $2.50. We can figure this out by dividing $15 by $2.50 since Haylie already paid $5 upfront.

$15 / $2.50 = 6

This means that Haylie and Marissa stayed for 6 hours and paid exactly $20 dollars each.
