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 |
