63) Betty borrows $60,000 at 12 percent compounded annually. The loan is to be repaid in five
equal annual end-of-year installments. How much must each loan payment be?
64) You are currently 25 years of age. You have developed a lifetime budget that includes
$50,000 at age 40 for a college fund for your kids and $25,000 per year for 20 years to
supplement your retirement, the first payment on your 60th birthday and the last payment on
your 79th birthday. You open an investment account on your 25th birthday that promises to pay
9% interest compounded annually. You want to deposit equal annual amounts into the account
every year on your birthday, starting today (your 25th birthday) and continuing until you are 40
years old (i.e., the last deposit is made on your 40th birthday). How much will each deposit have
to be if you want to meet your financial goals?
65) 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?
