Suppose that $4960 is invested at an interest rate of 35% per year, compounded continuously. What is the account balance after 46 years?

Using LaTeX:  \displaystyle P=P_0e^{kt} gives LaTeX:  \displaystyle P=4960e^{\frac{7 t}{20}} . Evaluating at LaTeX:  \displaystyle t=46 gives LaTeX:  \displaystyle P=48710527773 dollars.
