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.  
NPV of an investment:  
NPV = PV of Cash inflows - PV of cash outflow  
<em>Present value of cash inflows:</em>
A × 1-(1+r)^(-n)/r
A- annual cash inflow-20,000   r-rate of return-10%, n-number of years-6
PV of cash flow = 20,000 × (1.1)^(-6)/0.1 = 87,105.21399
<em>PV of scrap value</em>
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=   $49,234.16  
NPV = $49,234.16

Answer:    
Lower interest rates – reduce cost of borrowing and increase consumer spending and investment.
Increased real wages – if nominal wages grow above inflation.
Higher global growth – leading to increased export spending.
Devaluation, making exports cheaper and imports more expensive, increasing domestic demand.
Explanation:
Some ways you can help the economy are 
1. Lower interest rates – reduce cost of borrowing and increase consumer spending and investment.
2. Increased real wages – if nominal wages grow above inflation.
3. Higher global growth – leading to increased export spending.
4. Devaluation, making exports cheaper and imports more expensive, increasing domestic demand.
