You belong to a gym where the base membership is $36 per month and each group fitness class you take costs an additional $2.25 per class. write a function in x that represents the total amount you spend on your gym membership in a month. be sure to indicate any domain restrictions.

C(x) = 36 + 2.25x

Step-by-step explanation:

Given,

Base membership price = $ 36,

Additional cost per class = $ 2.25,

If x represents the number of classes in gym,

Then the total amount spent on gym membership in a month ( say C(x) ) = membership price + additional cost for x classes

⇒ C(x) = 36 + 2.25x

Which is the required function.
