Question

To join a gym, there is a monthly fee of $12 and a $5 fee per workout class you take. Which of the following functions would show the cost, in dollars, for a month that she takes w workout classes?

C(w) = 12w
C(w) = 5w + 12
C(w) = 12 + 5w
C(w)= 17w

Answer 1

`C(w) = 5w + 12`

`C(w) = 12+5w`

Explanation:

Given information:

- Monthly fee of $12

- $5 fee per workout class

-
`w` represents the workout classes taken for a month

- - - -

With the given information, we can conclude that
`C(w)=` workout fee + monthly fee.

Workout fee =
`$5w`

Monthly fee =
`$12`

∴
`C(w) = 5w + 12` or
`C(w) = 12+5w` (they are the same)

Hope this helps :)
