    then: A= 48961e^12.675 A= 48961*319655.78 A= 15650666514.54 (U see, this is soooo not right!) :/

    I can think of a long way to do it. 48961- (0.025*48961)=A(customer base after 1 year) A-(0.025*A)=B(customer base after 2 years) B-(0.025*B)=C(3 years.....) and so on. There is probably an easier way to solve this with n! or something, but I don't know off hand.

    ^^ that's basically the way to do it Since it's continuously declining, you can also use: \(\large y=Ce^{kt} \) where C is your initial number of customers and k = -0.025. Plug in t=13 and you should get 35375.66
