4. FinTronics currently uses an machine is being depreciated on a straight-line basis to a zero salvage value and it has six years of remaining depreciable life (two years have already passed) and its current market value is $3,000. If FinTronics keeps the old machine it would have no salvage value in six years. injection-molding machine that was purchased two years ago for $24,000. The FinTronic ha been offered a replacement machine that has a cost of $24,000, an estimated useful life of six years, and an estimated salvage value of $800. This machine will be depreciated straight-line to a zero salvage value over six years. The new machine would permit an output expansion, so sales would rise by $1,000 per year. Even with the sales increase, its much greater efficiency would cause operating expenses to decline by $1,500 per year. The new machine would require that inventories be increased by $2,000, but accounts payable would simultaneously increase by $500. All working capital will be recovered at the end of the project. FinTronics' tax rate is 34 percent and its cost of capital is 15%. Should FinTronics replace the machine? (10 pts.)
