What are the Investment options for retirement plans

Today is January 1 and an individual is currently 30 years old. She made $93,000 last year and she estimates she will need 75% of her current income in today\'s dollars to live on when she retires. She believes that inflation will average about 3.6 percent per year during her working years. (For simplicity we will ignore inflation during her retirement years). She will retire at age 65 and will begin drawing down her retirement annuity at age 65.

a) How much money will she need to withdraw each year starting at age 65 to have the same purchasing power as today? Round your answer to the nearest penny.

b) She plans on making a total of 20 annual withdrawals after she retires. After she retires she believes she will be able to earn 5.9 percent per year. How much must she have at age 65 in order to make her planned withdrawals? Round your answer to the nearest penny.

c) If she puts her money in a blended stock and bond portfolio now, she figures she can earn 11 percent per year until she retires. How much should she save per year starting right now in order to have the retirement annuity she desires? Round your answer to the nearest dollar.
