Question: An investment bank gives 10 percent interest at the end of every month. How much money in total will you have, including interest, at the end of 2 months if you invest $300? Think carefully first, then make a decision:
After the first month you get 10 / 100 * $300 = $30 interest. After the first month you will have $300 + $30 = $330 in total. After the second month you get = 10 / 100 * $330 = $33 interest. After the second month you will have $330 + $33 = $363 in total. So the answer is 363.
