One year$$ ago, your company purchased a machine used in manufacturing for $$90,000.$ You have learned that a new machine is available that offers many$$ advantages; you can purchase it for $$170,000$ today. It will be depreciated on a$$ straight$-$line basis over ten years and has no salvage value. You expect that the new machine will produce a gross margin$($revenues minus operating expenses other than$$ depreciation$)$ of $$45,000$ per year for the next ten years. The current machine is expected to produce a gross margin of $$21,000$ per year. The current machine is being depreciated on a$$ straight$-$line basis over a useful life of $11$ years, and has no salvage$$ value, so depreciation expense for the current machine is $$8,182$ per year. The market value today of the current machine is $$45,000.$ Your$$ company's tax rate is $40\%,$ and the opportunity cost of capital for this type of equipment is $10\%.$ Should your company replace its$$ year$-$old machine?
