Discount rate from Table 1 is .54027 (8 periods at 8%). Present value
of $30,000 to be received in 8 years discounted at 8% is therefore
$16,208.10 ($30,000 X .54027).
(b) i = 9%

Discount rate from Table 2 is 4.48592 (6 periods at 9%). Present
value of 6 payments of $30,000 each discounted at 9% is therefore
$134,577.60 ($30,000 X 4.48592).

Discount rate from Table 1 is .62092 (5 periods at 10%). Present value of
$600,000 to be received in 5 years discounted at 10% is therefore $372,552
($600,000 X .62092). Ramirez Company should therefore invest $372,552
to have $600,000 in five years.

Discount rate from Table 1 is .50187 (8 periods at 9%). Present value of
$700,000 to be received in 8 years discounted at 9% is therefore $351,309
($700,000 X .50187). LaRussa Company should invest $351,309 to have
$700,000 in eight years.

Discount rate from Table 1 is .68301 (4 periods at 10%). Present value of
$36,000 to be received in 4 years discounted at 10% is therefore $24,588.36
($36,000 X .68301). Polley should receive $24,588.36 upon the sale of the note.

Discount rate from Table 1 is .79383 (3 periods at 8%). Present value of
$60,000 to be received in 3 years discounted at 8% is therefore $47,629.80
($60,000 X .79383). Marichal Company should receive $47,629.80 upon issu-
ance of the zero-interest bearing note.

Discount rate from Table 2 is 9.71225. Present value of 15 payments of
$40,000 each discounted at 6% is therefore $388,490 ($40,000 X 9.71225).
Colaw Company should pay $388,490 for this annuity contract.
