Q. You want $100,000 after eight years in order to start a business. Currently you have $26,000, which may be invested to earn 7 percent annually. How much additional money must you set aside each year if se funds also earn 7 percent in order to meet your goal of $100,000 at end of eight years? By how much would your answer differ if you invested additional funds at beginning of each year instead of at end of each year?
