A machine purchased three years ago for $303,000 has a current book value using straight-line depreciation of $184,000; its operating expenses are $36,000 per year. A replacement machine would cost $239,000, have a useful life of nine years, and would require $12,000 per year in operating expenses. It has an expected salvage value of $76,000 after nine years. The current disposal value of the old machine is $88,000; if it is kept 9 more years, its residual value would be $15,000.Calculate the total costs in keeping the old machine and purchase a new machine.
