我用英文做解答吧，比较快。我想应该是这样做的。

 

initial setup costs = -8,000 - 2,000 = -10,000

 

income: [ sales - costs - depreciation ] * (1-tax)

[5000-2000-2000] * (1-.4) = 600

 

NPV: since depreciation does not affect CASH flows, then add back 2000 to 600, resulting in 2600 as cash inflows per year.

 

use your calculator

CF0 = -10,000

C01 = 2600

F01 = 5

 

I = 10

[CPT] NPV = -143.954
