A manufacturing process can be designed for varying degrees of automation. The following is relevant cost information. Determine which is best by after-tax analysis using an income tax rate of 28%, an after-tax MARR 0f14%, and SL depreciation. Assume that each has a life of four years and no BV or MV. r: A $9,000 $8,500 $600 B 16,000 8,000 700 C 20,000 5,000 1,300 D 33,000 2,500 1,700 a Click the icon to View the interest and annuity table for discrete compounding when the MARR is 14% per year. Calculate the AW value for the Degree A. AWA(14%) = 3 (Round to the nearest dollar.)
