Question
Two mutually exclusive design alternatives are being considered. The estimated cash flows for each alternative are
given below. The MARR is 10% per year. The decision-maker can select one of these alternatives or decide to select
none of them. Make a recommendation based on the following methods.
Design Y
Investment cost
Annual revenue
Annual cost
Useful life
Salvage value
Net PW
a. Based on PW method, Design
b. The modified B/C ratio of Design Y is
The modified B/C ration of Design Z is
is more economical.
$140,000
$43,705
$7,881
d. The discounted payback period of Design Y is
The discounted payback period of Design Z is
Design Z
c. The incremental B/C ratio is (Round to two decimal places)
Therefore, based on the B/C ratio method, Design
$275,000
$86,582
$27,683
15 years
15 years
$14,700
$33,000
$135,999 $180,890
(Round to two decimal places)
(Round to two decimal places)
is more economical
years (Round to one decimal place)
years (Round to one decimal place)
Therefore, based on the payback period method, Design would be preferred.
(e) Why could the recommendations based on the payback period method be different from the other two methods?
A. because the payback period method ignores the cash flows after the payback period
B. because the payback period gives more weight to the cash flows after the payback period
