Question

How much money invested at 5% compounded continuously for 3 years will yield $820?

Answer 1

I calculated 1.05 to the power of three then divided $820 by this number. I think this will convert the original amount into the amount with the compound interest. I hope this helps,

Answer 2

\[A=Pe^{rt}\]
\[\frac{A}{e^{rt}}=P\]

Answer 3

\[Ae^{-rt}=P\]
which is the same thing of course :) just looks nicer
