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
First plug in the equations, then simplify/cancel out terms until you get the answer
