Problem 9 4.5 points Zeon, a large profitable corporation, is considering adding some automatic equipment to its production facilities. An investment of $120,000 will produce an initial annual benefit of $29,000, but the benefits are expected to decline $3,000 per year, making secondyear benefits $26,000, third-year benefits $23,000, and so forth. If the firm uses sumof-years'-digit depreciation, an 8-year useful life and $12,000 salvage value, assuming that the equipment can be sold for its $12,000 salvage value at the end of the 8 years, will it obtain the desired 6% after-tax rate of return? Assume an incremental tax rate of 46%.
