4. (35 points) A mechanical engineer is comparing three alternative processes for increasing the efficiency of a wastewater treatment facility. The costs and benefits determined for the three alternatives are listed in the table below. The interest rate is 8% and each of the processes being analyzed has a life of 12 years. (please show your cash flow diagram for each alternative.) Mechanical Processes for Wastewater Treatment Facility Alternative Initial Cost Yearly Benefit Process l151,800,000.00-152 75,000.00 Process 2 $1,300,000.00 $150,000.00 increasing by $10,000.00 $200,000.00 Resale Value at the End of 12 Years $300,000.00 year starting at year2 Process 3 $1,200,000.00 $110,000.00 $250,000.00 Determine which alternative should be chosen
