The Imperial Chemical Company is considering purchasing a chemical analysis machine worth $$13,000.$ Although the purchase of this machine will not produce any increase in sales revenues, it will result in a reduction of labour costs. In order to operate the machine properly, it must be calibrated each year. The machine has an expected life of $6$ years, after which it will have no salvage value. The following table summarizes the annual savings in labour cost and the annual maintenance costs in calibration over $6$ years:
