value is $$2,100,$ and it can be sold for $$2,400$ at this time. Thus, the annual depreciation expense is $$2,\frac{100}{6}=$$$350$ per year. If the old machine is not replaced, it can be sold for $$500$ at the end of its useful life. The replacement machine would permit an output expansion, so sales would rise by $$1,000$ per year; even so$,$ the new machine's 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 $$800.$ Dauten's marginal federal$-$plus$-$state tax rate is $25\%,$ and its WACC is $11\%.$
