(5 points) A farmer is considering replacing a labor-intensive machine system with a more capital-intensive one. Adopting the new system is estimated to increase machinery operating expenses by about $21,000 per year. The new machinery will cost $30,000 plus $5,000 for shipping and installation; however, the trade-in value of the old system is $10,000. Adopting the new machinery will result in annual depreciation of 33.33% in year 1,44.45% in year 2 , 14.81% in year 3 , and 7.41% in year 4. The farmer forecasts that revenues will increase by $41,000 for each of the 4-year planning horizon, with zero salvage value and a 20% tax rate.
