At the bowling alley, David paid $18 and bowled 4 games while Jennifer paid $15 and bowled 3 games. Both of the prices include the price of renting shoes.

Question

The cost per game is $:__

The show rental cost is $:__

Answer 1

Cost per game = (Total cost - Shoe rental cost) / Number of games bowled

David: (18 - X) / 4 = 18
Jennifer: (15 - X) / 3 = 15

Solving for X:

David: (18 - X) = 72
18 - X = 72
-X = 54
X = -54

Jennifer: (15 - X) = 45
15 - X = 45
-X = 30
X = -30

Since the shoe rental cost cannot be negative, let's consider the positive values for X:

Cost per game is $12 and Shoe rental cost is $6.
