Answer

Answer 7. All else held constant, the future value of a lump sum investment will decrease if the interest is changed to simple interest from compound interest. If Interest method is changed to simple interest then the interest is calculated on investment made instead of the balance in the account which include both interest and invement. Answer 15. For the first 13 years, interest rate is 13% and for next 12 years interest rate is 6%. So Future Value = 5500 * 1.092 ^ 13 * 1.06 ^ 12 Future Value = $34,747.80 Answer 16. Future Value of investment made 11 years ago = $3,200 * 1.092^4 * 1.055^7 Future Value of investment made 11 years ago = $6,619.23 Future Value of investment made 7 years ago = $1,000 * 1.055^7 Future Value of investment made 7 years ago = $1,454.68 Total Future value = $6,619.23 + $1,454.68 = $8,073.91 Answer 17. Let n be the age. So, $1,500 * 1.053^n = $42,856 1.053^n = 28.571 n = ln(28.571) / ln(1.053)

n = 64.91 years
