Question

4) The cost of membership at local country club is $125 per family member per month. Each family also has to pay $75 in service fees. Model the cost, C, for a membership for a family with x members. A) C(x) = 75x B) C(x) = 125x C) C(x) = 125x + 75 D) C(x) = 125 + 75x

Answer 1

C) C(x) = 125x + 75

Explanation:

The membership of the local country club costs $125 per family member, since don't know the exact number of members, we will put an x next to 125 to describe per. The $125 cost increases as x increases. Each family, no matter what, has to pay 75 dollars, so we don't have to put a variable next to it because it is guaranteed.

Answer 2

C(x)=125x+75
You multiply 125 by how many family members and and the 75
