3. An industrial coal-fired boiler for process steam is equipped with a 10-year-old electrostatic precipitator (ESP). Changes in coal quality have caused stack emissions to be in noncompliance with federal standards for particulates. Two mutually exclusive alternatives have been proposed to rectify this problem (doing nothing is not an option). Capital investment Annual operating expenses Useful Life New Baghouse $1,140,000 $115,500 10 years New ESP $992,500 $73,200 10 years The MARR is 9% per year. Make a recommendation regarding which alternative to select.
