a) If Kim withdraws $75,000 annually, how long will her funds last?

b) To make the funds last 25 years, how much can Kim withdraw annually?

c) Kim is considering a two phase withdrawal where she withdraws $60,000 annually for 10 years, and then $35,000 thereafter (when social security starts). How long will her funds last assuming that the 9% rate of return (EAR) is accurate for both phases of the retirement plan.
