2.  Suppose you start working at age 21 and work until age 6 and your job pays $59,000.  Assume you get paid once a year at the end of the year and assume your annual salary increases by 3% per year.    Each year, you intend to invest a constant proportion of your salary in an investment account paying 6% annual interest.  

You withdraw your 1st retirement check at age 68 and intend to live for 15 years.  You want your first retirement check to be 70% of what you made at age 67, and you want your retirement benefit to increase by 3% per year.  What proportion of your salary do you need to invest per year to meet your retirement needs?
