Basic replacement problem. The Virginia company is considering replacing a riveting machine with a new design that will increases earnings before depreciation from $20,000 per year to $51,000 per year. The new machine will cost $100,000 and has an estimated life of eight years, with no salvage value. The applicable corporate tax rate is 40% and the firms cost of capital is 12%. The old machine has been fully depreciated and has no salvage value. Should it be replaced with a new machine?
