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 pinups, 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 $-26.N0 $-25, 518 $-24, 900 $-13, 140 -12, 831 The annual worth for years I through infinity of $50,000 now. $10,000 per year in years 1 through 15, and $20,000 per year in years 16 through infinity at 10% per year is closest to: less than $16, 900 $16, 958 $17, 395 $18, 575 $19, 100
