The initial cost of a packed-bed degassing reactor for removing trihalomethanes from potable water is $84,000. The annual operating cost for power, site maintenance, etc. is $13,000. If the salvage value of the pumps, blowers, and control systems is expected to be $9000 at the end of 10 years, the AW of the packed-bed reactor at an interest rate of 8% per year is closest to:
