Raytheon wishes to use an automated environmental chamber in the manufacture of electronic components. The chamber is to be used for rigorous reliability testing and burn-in. It is installed for $1.4 million and will have a salvage value of $200,000 after 8 years. Its use will create an opportunity to increase sales by $650,000 per year and will have operating expenses of $250,000 per year. Corporate income taxes are 40 percent. Develop tables using a spreadsheet to determine the ATCF for each year and the after-tax PW, AW, for 8 years. After-tax MARR is 10 percent. Use 7- years class depreciation for MACRS and IRR if the chamber is kept
