Case C-William is 24 years old now. William wants to retire at age 50 and receive $80,000 per year at the end of each year for 40 years (at the end of his 50th through 89th year hoping that he will live to age 90). William plans to invest money into a retirement annuity at the end of each year from age 24 to age 49. William wants to leave $200,000 to his children when he dies. The annuity earns 8% interest compounded annually. Prepare a spreadsheet for this fund from age 24 to age 90 showing the following each year: 1. William's age each year 2. The beginning balance each year 3. The amount deposited (ages 24 - 49) or withdrawn (ages 50 - 89) each year 4. The amount of interest earned each year 5. The ending balance each year (which should be $200,000 when William becomes 90)
