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
