70) Bob invested $2,000 in an investment fund on his 21st birthday. The fund pays 7% interest
compounded semiannually. Bob is celebrating his 50th birthday today. Bob decides he wants to retire on
his 60th birthday and he wants to withdraw $75,000 per year, the first withdrawal on his 60th birthday
and the last withdrawal on his 90th birthday. Bob expects to receive $100,000 from his employer on his
55th birthday in recognition of his long service to the company. Assume Bob has not taken any money
out of his investment fund since he initially funded it on his 21st birthday, and that he will deposit the
$100,000 from his employer into the investment fund on his 55th birthday. The investment fund will be
used to pay for Bob’s retirement.
If Bob makes no additional deposits into his investment fund, how much will be available for retirement
at age 60?
Since the amount in (a) is insufficient to meet his retirement goals, Bob decides to deposit equal annual
amounts into the investment fund beginning on his 51st birthday and ending on his 59th birthday, so that
he can meet his retirement goals. How much will each deposit be?

71) Bill starts a retirement fund at age 21 and plans on depositing equal annual amounts on each
birthday, starting at age 21, and ending at age 60. He wants to have $2 million at age 60. John starts his
fund on his 30th birthday. He wants to deposit equal annual amounts on each birthday starting on his
30th birthday and ending on his 60th birthday. John wants to have $2 million at age 60. If the investment
funds earn 10% per year, calculate the amounts the Bill and John respectively will have to save each year
(rounded to the nearest dollar) to meet their goals. Comment on the difference.
