A mechanical engineer who designs and sells equipment that automates manual labor processes is offering a machine/robot combination that will sig­nificantly reduce labor costs associated with manu­facturing garage-door opener transmitters. The equipment has a first cost of $170,000, an estimated annual operating cost of $54,000, a maximum use­ful life of 5 years, and a $20,000 salvage value any­time it is replaced. The existing equipment was pur­chased 12 years ago for $65,000 and has an annual operating cost of $78,000. At most, the currently owned equipment can be used 2 more years, at which time it will be auctioned off for an expected amount of $6000, less 33% paid to the company handling the auction. The same scenario will occur if the currently owned equipment is replaced now.
