Gina rented a moon walk for 5 hours at total cost of $230. lori rented the same moon walk for 2 hours at a total cost of $125. the cost of renting is based upon flat set up fee? plus rental fee?

Assuming both rented from the same store and the rental price is the same.

$230 -  $125 = $105
5hours - 2hours = 3hours
3hours = $105
1 hour = $105 ÷ 3 = $35
So the price of 1 of one hour rental is $35.

2hours = $35 x 2 = $70
Lori paid $125
Therefore the flat setup fee = $125 - $70 = $55

Ans:  Setup fee = $55, rental fee = $35/hour
