Marissa and haylie met for dinner in downtown Savannah. Marissa did flat-rate valet parking for $20. Haylie went to another vale
t 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?
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.
