**drwls**, Saturday, April 30, 2011 at 9:04am1) The balance after one year with compounding is increased by a factor

(1 +(.09/12)^12 = (1.0075)^12 = 1.093807

The effective annual interest rate is therefore 9.3807%

2) 8500*(1.093807)^5 = $ 13,308.29

3) After two years and withdrawing $5000, she is left with

8500*(1.093807)^2 - 5000

= 10,169.52 - 5000 = 5169.52

After three more years, that becomes

5159.52*(1.093807)^3 = $ 6751.98
