A tennis club offers two payment options:
Option1: $35 monthly fee plus $4/hour for court rental
Option 2: No monthly fee but $6.50/hour for court rental.
Let x = hours per month of court rental time.
a) Write a mathematical model representing the total monthly cost, C, in terms of x for the following:

What exactly is your question? You've provided some information but haven't asked a question.

you make it a equation with (f)x its really not hard

Do you want to know which plan is best? That depends upon how many hours you plan to play per month. If X = # of hours played per month, then set
35 + 4 X = 6.50 X
2.50 X = 35
X = 14
Option 1 is the best plan for those playing 14 hours or more per month.
