Suppose that $12207 is invested at an interest rate of 11% per year, compounded continuously. What is the account balance after 25 years?

Using LaTeX:  \displaystyle P=P_0e^{kt} gives LaTeX:  \displaystyle P=12207e^{\frac{11 t}{100}} . Evaluating at LaTeX:  \displaystyle t=25 gives LaTeX:  \displaystyle P=190950 dollars.
