"Suppose you invest $1500 at an annual interest rate of 5% compounded continuously. How much will you have in the account after 4 years?" The formula for continuous compounding is A = Pe^(rt), where P is the initial investment, r is the interest rate as a decimal fraction, and t is the # of years.
Here, A = $1500e^(0.05[4]), or $1500e^0.20. This comes to $1832.10.
