Consider two air-conditioning systems with the cash flow estimates as given below. Use AW analysis to determine the sensitivity of the economic decision to MARR values of 4%,6%, and 8% per year. The annual worth of air-conditioning system 1 when the MARR is 4% is $ The annual worth of air-conditioning system 2 when the MARR is 4% is $ The annual worth of air-conditioning system 1 when the MARR is 6% is $ The annual worth of air-conditioning system 2 when the MARR is 6% is $ The annual worth of air-conditioning system 1 when the MARR is 8% is $ The annual worth of air-conditioning system 2 when the MARR is 8% is $ When the MARR is 4% is selected. When the MARR is 6% is selected. When the MARR is 8% is selected
