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 these funds also earn 7 percent in order to meet your goal of $100,000 at the end of eight years? By how much would your answer differ if you invested the additional funds at the beginning of each year instead of at the end of each year?
