FFF, Inc. owns a machine that it uses in manufacturing a product. The original cost of the machine was $600,000. It has a current book value of $200,000. The machine has 3 years of useful life remaining. They can purchase a new machine to replace the current machine for $500,000 that has no salvage value at the end of its 3- year useful life. If they purchase the machine, variable operating costs would be reduced from $200,000 per year to $150,000 per year. FFF could sell the old machine for $50,000.

Should FFF sell the old machine and purchase the new machine?
