The formula for the FV of an investment with continuous compounding is Pe^rt.

With P of 1,800, r of 7.1% and t of 15, and e a constant of 2.71828:

rt = 1.065, and e = 2.71828, so 2.71828^1.065 = 2.900837 x 1,800 (P) = 5,222.

Suppose you invest 1800 at an annual interest rate of 7.1% compounded continuously. How much will you have in the account after 15 years

How much money invested at 45% compounded continuously for 12 years will yield 5000$?

How long will it take for an investment with a principal of 5000 to reach 15,000 with an annual interest rate of 14.5 %compounded continuously
