Answer:
The closest answer is option A,$7649
Explanation:
The net present value of the investment is the present value of annual cost savings minus the initial cost of investment.
present of cash flow=cash flow/(1+r)^n
r is the discount rate of 12%
n is the year the cash flow relates to ,for instance year zero for the initial investment
NPV=-$54,000+$16,000/(1+12%)^1+$16,000/(1+12%)^2+$16,000/(1+12%)^3+$16,000/(1+12%)^4+($16,000+$7,000)/(1+12%)^5=$ 7,648.41
note that the project gives $7,000 in salvage value in year 5
