The function m(n) = 20(1.2)n – 1 approximates the number of members in a club n years after it was started, and the function f(n) = 15 models the yearly fee each member pays during year n.

Which function approximates the total amount of money collected for yearly fees in year n?

t(n) = 360n – 1

t(n) = 300(1.2)n – 1

t(n) = 35(1.2)n – 1

t(n) = 20(1.2)n – 1+15
