Always assume compound interest unless the problem says otherwise. Round all answers to two decimals. Show your work suppose you have $500 to invest and you believe that you can earn 8% per year over the next 15 years. Assuming the interest compounds annually, how much will your initial $500 be worth at the end of 15 years? 1. How much would this $500 be worth using simple interest?
