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 $$1,320,000$ and will have a salvage value of $$160,000$ 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. All dollar

amounts are expressed in real dollars. Depreciation follows MACRS $5-$year property, taxes are $25\%,$ the real after$-$tax MARR is $10\%,$

and inflation is $3\mathrm{.}2\%.$
