Membership to a racket ball club has an application fee and a monthly fee that can be modeled by the function c (m) = 12.50m + 49, where m is the number of months of membership. The club is running a special in which the application fee is being waived as well as the first month's payment. This can be modeled by the function s (c) = c - 12.50.

Which function can be used to determine the total amount paid by someone who joined during the special depending on the number of months of membership?

s (c (m)) = m

s (c (m)) = 12.5m

s (c (m)) = m - 12.5

s (c (m)) = 12.5m - 12.5
