A machine's current book value is $600. The machine cost $1300 three years ago. Operating expenses have been $380 per year, and the machine could last for three more years. Because of a breakthrough in design, a replacement machine would save $300 per year can be purchased for $1000 and has an expected service life of eight years. The scrap value of either machine at any time after installation is $100. If the IRS allows straight line depreciation over a six year period for this type of machinery and if an after tax MARR of 12% is applicable, should the current machine be replaced? The company's tax rate is 52%.
