Answer:
The NPV of the project at 8.7 percent will be 4,802.58
Step-by-step explanation:
We will calcualte the present value of the cash inflow:
 
 
year 3: 
 Inflow 11,900.00 
 time 3.00 
 rate 0.087
 
 
 PV 9,265.28
Year 4:
 Inflow 11,900.00 
 time 4.00 
 rate 0.087
 
 
PV 8,523.71 
Year 6: 
 Inflow 50,500.00 
 time 6.00 
 rate 0.087
 
 
 PV 30,613.58 
Then, we will add them together and subtract the investment amount
NPV: 30,613.59 + 8,523.71 + 9,265.28 - 43,600 = 4,802.58
