The corporation is a profitable one that has a 22% combined incremental tax rate. At the end of 5 years the mining company changed its method of operation and sold the production machinery for $40,000. During the 3 years the machinery was used, it reduced mite operating costs by $32,000 a year, before taxes.

The machinery will have no salvage value, as the cost to remove it will equal its scrap value. The uniform annual benefits from the machinery are $15,000. For a combined 45% income tax rate, and 100% bonus depreciation, compute the after-tax rate of return. 12-24 A farmer bought a new harvester for $120,000. The harvester's operating expenses averaged $10,000 per year but the harvester saved $40,000 per year in labor costs.
