A machine purchased a year ago for $85,000 costs more to operate than anticipated. At the time of the purchase, it was expected to be used for 10 years with annual maintenance costs of $22,000 and a salvage value of $10,000. However, last year, it incurred a cost $40,000, which is expected to escalate to $41,200 this year and increase by $1,200 each year thereafter. The market value is now estimated to be $74,000-$10,000k, where k is the number of years since the machine was purchased. It is now estimated that the machine will be useful for a maximum of 5 more years. A replacement study is to be performed. Determine the values of P, n, AOC for year 5 and S of this defender. The value of Pis $ 54,000 The value of n is 4 years. es The AOC for year 5 is 66,000 The value of Sis $ 27,000
