Rader Railway is determining whether to purchase a new rail setter, which has a base price of $432,000 and would cost another $52,000 to install.The setter falls into the MACRS 3-year class, and it would be sold after three years for $220,000.Using the setter requires a $22,000 increase in net working capital.Although it would have no effect on revenues, the setter should save the firm $185,000 per year in before-tax operating cost (excluding depreciation).Raders marginal tax rate is 40 percent, and its required rate of return is 14 percent.Should the setter be purchased?
