Answer:
NPV = 37,599 Negative
Explanation:
We can calculate the NPV of the new sewing machine by deducting the Present value of future cash inflows by Investment
Initial investment = Machine cost + Training cost - Salvage value
Initial investment = 2,450,000 + 85,000 - 250,000
Initial investment = 2,285,000
Year                    DF(9%)  Present Value
1  Cash inflow   390,000  x 0.917    $357,798
2 Cash inflow   400,000  x 0.842   $336,672
3 Cash inflow   411,000  x  0.772   $317,367
4 Cash inflow   426,000  x 0.708   $301,789
5 Cash inflow   334,100  x 0.650   $217,077    (434,100 - 100,000)
6 Cash inflow   435,000  x 0.596   $259,376
7 Cash inflow   436,000 x 0.547   $238,507
7 Salvage value 400,000 x 0.547 Â Â $218,814 Â
  Â
Present Value of cash inflow       $2,247,401
Initial investment                 $2,285,000
NPV ($2,247,401 - $2,285,000) Â Â Â Â Â (37,599) Â Â
Conclusion: Hillsong should not purchase the new machine as the NPV of the machine is negative   Â
