Zoon, a large, profitable corporation, is considering adding some automatic equipment to its production facilities. The equipment costs $120,000 and will produce an initial annual benefit of $29,000, but the benefits are expected to decline $3000 per year. The firm uses sum-of-years-digits depreciation over the 3-year useful life of the equipment which has a $12,000 salvage value. Using present worth analysis, determine whether the equipment should be purchased if the after-tax MARR is 6%. Assume that the equipment can be sold for its S12,000 salvage value at the end of the 3 years. Also, assume a 46% income tax rate.
