You have purchased a machine costing $34,000. The machine will be used for two years, and at the end of this time, its salvage value is expected to be $15,000. The machine will be used 8,000 hours during the first year and 9,000 hours during the second year. The expected annual net savings will be $39,000 during the first year and $48,000 during the second year. If your interest rate is 11%, what would be the equivalent net savings per machine hour?
