Suppose that $8379 is invested at an interest rate of 24% per year, compounded continuously. What is the account balance after 43 years?
Using \(\displaystyle P=P_0e^{kt}\) gives \(\displaystyle P=8379e^{\frac{6 t}{25}}\). Evaluating at \(\displaystyle t=43\) gives \(\displaystyle P=254162365\) dollars.
