Equipment that was purchased by Newport Corpo­ration for making pneumatic vibration isolators cost $90,000 two years ago. It has a market value that can be described by the relation $90,000 ? 8000k, where k is the years from time of purchase. The operating cost for the first 5 years is $65,000 per year, after which it increases by $6300 per year. The asset’s sal­vage value was originally estimated to be $7000 after a predicted 10-year useful life. Determine the values of P, S, and AOC if (a) a replacement study is done now and it is assumed that the equipment will be kept a maximum of only 1 more year, and (b) a replacement study is done 1 year from now and it is assumed that the equipment will be kept a maxi­mum of only 1 more year after that.
