Answer: $516
Explanation:
Net Present value is the present value of inflows less present value of outflows.
The project has annual inflows of $54,000 except in 4th year where it will have inflows of $65,000 because the salvage value will be added to the inflows.
Present value of inflows = 54,000/1.12 + 54,000/1.12² + 54,000/1.12³ + 65,000/1.12⁴
= $160,516
Net Present Value = 160,516 - 160,000
= $516
