Alan writes the equation A=500(1.25)t to figure out how much it will cost him for a one-year loan of $500 with an interest rate of 25% compounded only once. He wants to determine the annual percentage rate (APR) for a loan that would cost the same amount overall, if it is compounded monthly, instead of only once. Which equation should he use, and what is the APR? A≈500(1.2512)112t≈14.55% A≈500(1.0188)12t≈1.88% A≈500(1.0188)12t≈22.56% A≈500(1.25)12t≈1.88%
