Check my work 9 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 $32,000, which is expected to escalate to $33,900 this year and increase by $1,900 each year thereafter. The market value is now estimated to be $63,000-$12,000k, where k is the number of years since the machine was purchased.
