Since the  cost of capital is 7. 5% and the tax rate is 22%., the present value of the cost of the equipment is  $635,811
The cost of the equipment is given as $ 644, 000
The stated cost of the asset is guven as $ 46 000
The years that the installation would last is the life = 5 years
We have to solve for the depreciation
The cost of asset / life
$ 46 000 / 5 years
= 9200 dollars
We have to solve for the tax saving. This is
depreciation * Â tax rate
= Â 9200 dollars * 22%.
= $2024
we have to solve for the present value of tax saving by using the formula
=PV(rate, nper, -pmt)
The present value of tax saving is given as $ 8188.87
The present value of the cost of the equipment = Â equipment cost - present value of tax saving
= $644,000 - $ 8188.87
= $635,811
