Your employer does not offer a pension plan, and you determine that you'll need to save on your own for retirement. You are 35 years old and expect to work till you are 65 years old. Currently, you have not started saving for retirement, but you're expecting to save $10,000 per year for each of the years to retirement. 

a) Assume that you can earn a return of 8% annually in the market. How much money would you expect to have when you reach retirement age? 

b) Assume you had a starting investment of $100,000, and your savings for retirement are expected to earn an average of 6% per year. What would you expect your total retirement savings to equal at age 65? 

c) Assume your answer in a) is correct. You want to leave your estate with $250,000 (present value) upon your death. If you anticipate that you will die at age 85, how much could you withdraw per year, in order to leave a final balance of $250,000 (present value)? Assume your investments earn an average of 4% per year during your retirement.
