Suppose you invest $1500 at an annual interest rate of 3.4% compounded continuously. How much will you have in the account after 30 years?

Your $1,500 should be worth=$4,159.79 after 30 years @ 3.4% comp. continuously.

I agree with Guest1 ,....here is the calculation:

FV = PV e^(.034n) = 1500 e^(.034 x 30)= 4159.79
