At the beginning of the year, a company purchases a special-purpose molding machine for $600,000 cash including installation costs. The machine should have a useful life of three years with zero residual value. The budgeted income statement for the coming year, including the depreciation on the new machine, is shown below: Revenue Cash operating expenses Straight-line depreciation Operating income $2,000,000 1,260,000 200.000 $540,000 Immediately after the purchase of the new molding machine, a different molding machine became available. This newer machine would save $150,000 cash operating costs per year and could be installed in the plant immediately at a cost of $750,000. This machine would also have a useful life of three years with zero residual value. The annual depreciation amount of the new machine would be $250,000. The "old" machine could be sold for $120,000. There is no trade-in option. Using only relevant costs and desiring to minimize costs, should the company keep the "old" machine or replace it, considering the three years together? (Ignore the time value of money) $150,000 in favor of replacing the "old" machine. $30,000 in favor of replacing the "old" machine. $180,000 in favor of keeping the "old" machine. $330,000 in favor of keeping the "old" machine
