Solution :
Calculating the (NPV) Net Present value for the following matters to check the feasibility of the replacement of an 8 year old riveting machine with the new one :
Let
A = Year (n)
B = Initial outlay
C = Five-year MACRS depreciation percentage
D = Depreciation with MACRS Method (D)
E = Savings in earnings before depreciation
F = Taxable Income (earnings before depreciation - depreciation
G = Income taxes (Taxable Income *40%)
H = cash flow
I = PV of at the rate
=

8 0% 0 27000 27000 10800 16200 6542.91
NPV $22,329.39
As the NPV, the project is positive ($22,329.39) and so the company should replace the 8 year old riveting machine with the new one.
