a. Janine is 25 and has a good job at a biotechnology company. She currently has $5,000 in an IRA, an important part of her retirement nest egg. She believes her IRA will grow at an annual rate of 8 percent, and she plans to leave it untouched until she retires at age 65. Janine estimates that she will need $875,000 in her total retirement nest egg by the time she is 65 in order to have retirement income of $20,000 a year. (She expects that Social Security will pay her an additional $15,000 a year). How much will Janines IRA be worth when she needs to start withdrawing money from it when she retires?

b. How much money will Janine have to accumulate in her companys 401(k) plan over the next 40 years in order to reach her retirement income goal?
