Exercise B-18 (10 minutes)
a. p = present value of $60,000 at 9% for 4 years
b. p = present value of $15,000 at 8% for 2 years
c. There are at least two ways to solve this problem. (1) We can take the
$463 today, compute its future value, and then compare it to the future
value amount of $1,000. (2) We can discount the $1,000 back to the
present and compare it to the $463 today.
The same answer results: choose $463 today
f = future value of $463 at 9% for 10 years
p = present value of $1,000 at 9% for 10 years
d. f = future value of $90 at 5% for 8 years
e. f = future value of $158,500 at 10% for 8 years

Exercise B-18 (concluded)
f. There are two aspects to this problem: a present value of a lump sum
part and a present value of an annuity part.
Part 1: p = present value of $10,000 at 6% for 10 years
Part 2: p = present value of $400 annuity at 6% for 10 years
The answer is the sum of the present values from parts 1 and 2:
g. p = present value of $500,000 at 6% for 20 years
Instructor note: It can be useful to extend this problem and assume a 30% tax rate. In this
case the annuity after-tax declines to $350,000. Accordingly, the present value of the
after-tax amount is $4,014,465. Again, nothing near the $10 million winnings advertised.
