Four years ago, the Attaboy Lawn Mower Company purchased a piece of equipment. Because of increasing maintenance costs for this equipment, a new piece of machinery is being considered for the assembly line. Suppose a $6,000 MV is available now for the defender. Perform a before-tax analysis, using a before-tax MARR of 12%, to determine which alternative to select. Assume that MV of the defender=0 five years from now. Be sure to utilize a uniform gradient in your analysis of the defender. i Click the icon to view the cost characteristics of the defender (present equipment) and the challenger. Click the icon to view the interest and annuity table for discrete compounding when MARR = 12% per year. The EUACDefender is $ The EUAC Challenger is $ (Round to the nearest dollar.) (Round to the nearest dollar.) The better alternative is to keep the defender i More Info Challenger Purchase cost = $10,000 Maintenance = $150 per year Defender Original cost = $8,000 Maintenance = $500 in year one (four years ago) increasing by a uniform gradient of $100 per year thereafter MV at the end of life = 0 Original estimated life = nine MV at the end of life = $3,500 Estimated life = five years Print Done Four years ago, the Attaboy Lawn Mower Company purchased a piece of equipment.
