Answer:
NPV = $49,234.16
Explanation:
The Net present value (NPV) is the difference between the Present value (PV) of cash inflows and the PV of cash outflows. A positive NPV implies a good investment  project and a negative figure implies the opposite. Â
NPV of an investment: Â
NPV = PV of Cash inflows - PV of cash outflow Â
Present value of cash inflows:
A × 1-(1+r)^(-n)/r
A- annual cash inflow-20,000 Â r-rate of return-10%, n-number of years-6
PV of cash flow = 20,000 × (1.1)^(-6)/0.1 = 87,105.21399
PV of scrap value
F×  (1+r)^(-n)
F- scrap value
= 2,000× 1.1^(-6)= 1,128.94
Initial cost = $39,000
NPV = 87,105.21399 + 1,128.94 -39,000= Â $49,234.16 Â
NPV = $49,234.16
