You paid $120 for a membership to a racquetball club. Court time is $4 per hour. Write a model that represents your average cost per hour of court time as a function of the number of hours played. What is the horizontal asymptote of this model and what does the asymptote represent?

a. y = 0; This asymptote represents the minimum amount paid per hour of court time.

b. y = 4; This asymptote represents the minimum amount paid per hour of court time.

c. y = 0; This asymptote represents the total number of hours of court time that needs to be paid for.

d. y = 4; This asymptote represents the total number of hours of court time that needs to be paid for.
