A machine purchased three years ago for $305,000 has a current book value using straight-line depreciation of $183,000; its operating expenses are $31,000 per year. A replacement machine would cost $233,000, have a useful life of nine years, and would require $13,000 per year in operating expenses. It has an expected salvage value of $67,000 after nine years. The current disposal value of the old machine is $80,000; if it is kept 9 more years, its residual value would be $16,000.
