Answer:
The pretax cost savings for project to be profitable will be more than $2,059,794 for the 5 years of life.
Step-by-step explanation:
Installed cost = $790,000
Initial working capital = $77,000
Tax rate = 21%
Project discount rate = 10%
Estimated salvage value = $118,000
Depreciable amount :
Installed cost $790,000
Salvage value 118,000
Net $672,000
Annual depreciation = $134,400 ($672,000/5)
Working capital = $77,000
Pretax cost savings = $211,400 x 1.61051 x 1.21
= $2,059,794
