The total cost, in dollars, of membership in a fitness center is given by the function c(m) = 20m + 40, where m is the number of months a person is a member. In dollars, how much is the cost of a membership for 1 year?

To join a sports club, every new member pays an initial amount in addition to the monthly charges. The formula for total cost of the membership is, F (c) = 100 + 5a, where c is the total cost of the membership and a is the number of months for which the membership holds. The total money paid by a 2 year membership will be, $
