A bowling alley charges $15 per game. Customers are also charged an additional $3 to rent bowling shoes.

Which statement is true, based on the given description?

a The description shows a linear relationship, but not a proportional relationship.
b The description shows a linear relationship and a proportional relationship.
c The description does not show a linear relationship or a proportional relationship.
d The description shows a proportional relationship, but not a linear relationship.

The correct statement is d) The description shows a proportional relationship, but not a linear relationship.

In this case, the cost of renting bowling shoes is fixed at $3 per game, regardless of the number of games played. This indicates a proportional relationship because the additional cost is directly proportional to the number of games played.

However, the total cost of playing the game depends on both the cost per game and the additional cost for renting shoes. Since there are two components contributing to the total cost, it does not show a linear relationship.
