Answer:
The right equation to determine the NPW is:
= B) NPW = -20000 + 4000(P/A,6%,3) + 5000(P/F,6%,3)
Explanation:
a) Data:
Present value cost of production equipment = $20,000
Annual benefits = $4,000
Period of useful life = 3 years
MARR = 6%
Salvage value = $5,000
Present Value Annuity Factor for annual benefits for 3 years at 6% = 2.673
Present Value Factor for Salvage Value after 3 years at 6% = 0.840
Present Value Factor for the initial cost of investment = 1
Therefore, to obtain the NPW of the investment, the correct equation is:
B) NPW = -20000 + 4000(P/A,6%,3) + 5000(P/F,6%,3)
where NPW = Net Present Worth
P/A = Present Value Annuity Factor
P/F = Present Value Discount Factor
