A machine purchased three years ago for $317,000 has a current book value using straight-line depreciation of $180,000; its operating expenses are $36,000 per year. A replacement machine would cost $230,000, have a useful life of nine years, and would require $11,000 per year in operating expenses. It has an expected salvage value of $64,000 after nine years. The current disposal value of the old machine is $75,000; if it is kept 9 more years, its residual value would be $20,000. (Please provide step by step instructions for all and also on how you determine that operating expenses)
