24. Present value (LO3) Mr. Flint retired as president of Color Title Company but is currently
on a consulting contract for $45,000 per year for the next 10 years.
a. If Mr. Flint’s opportunity cost (potential return) is 10 percent, what is the present
value of his consulting contract?
b. Assuming that Mr. Flint will not retire for two more years and will not start to receive
his 10 payments until the end of the third year, what would be the value of his
deferred annuity?

26. Special compounding (LO5) Determine the amount of money in a savings account at the
end of five years, given an initial deposit of $3,000 and a 8 percent annual interest rate
when interest is compounded (a) annually, (b) semiannually, and (c) quarterly.

27. Annuity due (LO4) As stated in the chapter, annuity payments are assumed to come at the
end of each payment period (termed an ordinary annuity). However, an exception occurs
when the annuity payments come at the beginning of each period (termed an annuity due).
To find the present value of an annuity due, subtract 1 from n and add 1 to the tabular
value. To find the future value of an annuity, add 1 to n and subtract 1 from the tabular
value. For example, to find the future value of a $100 payment at the beginning of each
period for five periods at 10 percent, go to Appendix C for n = 6 and i = 10 percent. Look
up the value of 7.716 and subtract 1 from it for an answer of 6.716 or $671.60 ($100 ×
6.716).
What is the future value of a 10-year annuity of $2,000 per period where payments
come at the beginning of each period? The interest rate is 8 percent.
9-27. Solution:
Appendix C
FVA = A × FVIFA
28. Annuity due (LO4) Related to the discussion in problem 27, what is the present value of
a 10-year annuity of $3,000 per period in which payments come at the beginning of each
period? The interest rate is 12 percent.

29. Present value alternative (LO3) Your grandfather has offered you a choice of one of the
three following alternatives: $5,000 now; $1,000 a year for eight years; or $12,000 at the
end of eight years. Assuming you could earn 11 percent annually, which alternative should
you choose? If you could earn 12 percent annually, would you still choose the same
alternative?

30. Payment required (LO4) You need $23,956 at the end of nine years, and your only
investment outlet is an 7 percent long-term certificate of deposit (compounded annually).
With the certificate of deposit, you make an initial investment at the beginning of the first
year.

objective?
b. What amount could you pay at the end of each year annually for nine years to achieve
this same objective?

31. Quarterly compounding (LO5) Beverly Hills started a paper route on January 1, 2004.
Every three months, she deposits $300 in her bank account, which earns 8 percent annually
but is compounded quarterly. On December 31, 2007, she used the entire balance in her
bank account to invest in an investment at 12 percent annually. How much will she have on
December 31, 2010?

36. Solving for an annuity (LO4) Dr. Oats, a nutrition professor, invests $80,000 in a piece of
land that is expected to increase in value by 14 percent per year for the next five years. She
will then take the proceeds and provide herself with a 10-year annuity. Assuming a 14
percent interest rate for the annuity, how much will this annuity be?

37. Solving for an annuity (LO4) You wish to retire in 20 years, at which time you want to
have accumulated enough money to receive an annual annuity of $12,000 for 25 years after
retirement. During the period before retirement you can earn 8 percent annually, while
after retirement you can earn 10 percent on your money.

annuity?

38. Deferred annuity (LO3) Rusty Steele will receive the following payments at the end of
the next three years: $4,000, $7,000, and $9,000. Then from the end of the fourth year
through the end of the tenth year, he will receive an annuity of $10,000. At a discount rate
of 10 percent, what is the present value of all future benefits?
9-38. Solution:
First find the present value of the first three payments.
PV = FV × PVIF (Appendix B) i = 10%
Then find the present value of the deferred annuity.
Appendix D will give a factor for a seven period annuity (fourth
year through the tenth year) at a discount rate of 10 percent. The
value of the annuity at the beginning of the fourth year is:

This value at the beginning of year four (end of year three) must
now be discounted back for three years to get the present value of
the deferred annuity. Use Appendix B.
