Jenny has $400 in an account with an annual interest rate of 6% compounded annually. if jenny makes no deposits or withdrawals, how much money will be in her account at the end of 3 years?

The formula for this problem is A=P (1 + (r/n)) ^nt.

A is what you're trying to find. P=400 r=0.06 t=3 n=1, since it's compounded once per year.

Now plug in those values to get A=400 (1 + (0.06/1)) ^1*3

I get an answer of $476.41
