Compute the present value of a
$150 cash flow for the following combinations of discount rates and times: (Do not round intermediate calculations. Round your answers
to 2 decimal places.)

Present
Value


a. r = 12%, t
= 8 years

$

b. r = 12%, t
= 16 years


c. r = 6%, t
= 8 years


d. r = 6%, t
= 16 years


Explanation:
a. $150/(1.12)^{8} =
$60.58

b. $150/(1.12)^{16} =
$24.47

c. $150/(1.06)^{8} =
$94.11

d. $150/(1.06)^{16} =
$59.05

Compute the future value of a $150
cash flow for the same combinations of rates and times: (Do not round intermediate calculations. Round your answers
to 2 decimal places.)

Future
Value


a. r
= 12%, t = 8 years

$

b. r
= 12%, t = 16 years


c. r = 6%, t
= 8 years


d. r = 6%, t
= 16 years


Explanation:
a. $150 × (1.12)^{8} =
$371.39

b. $150 × (1.12)^{16} =
$919.56

c. $150 × (1.06)^{8} =
$239.08

d. $150 × (1.06)^{16} =
$381.05

In 1880 five aboriginal trackers
were each promised the equivalent of 100 Australian dollars for helping to
capture the notorious outlaw Ned Kelley. In 1994 the granddaughters of two of
the trackers claimed that this reward had not been paid. The Victorian prime
minister stated that if this was true, the government would be happy to pay
the $100. However, the granddaughters also claimed that they were entitled to
compound interest.

a.
