How much would $100 invested at 8% intrest compounded annually be worth after 15 years? round your answer to the nearest cent. do not include units in your answer a(t) = p(1 + r/n)^nt

Our P = 100, r = .08, n = 1 (annually means once a year), and t = 15.  Filling in accordingly, we have .  Simplifying a bit gives us    and  .  Raising that number inside the parenthesis to the 15th power gives us  .  Multiplying to finish means that A(t) = $317.22

Here is my answer, i'm sorry if you didn't understand my explanation
