A process control manager is considering two robots to improve materials-handling capacity in the production of rigid shaft couplings that make dissimilar drive components. Robot X has a first cost of $84,000, an annual M&O cost of $31,000, and $40,000 salvage value, and it will improve revenues by 596,000 per year. Robot Y has a first cost of $146.000, an annual M&O cost of $28.000. and $47000 salvage value, and it will increase revenues by $125,000 per year. The company's MARR is 25% per year, and it uses a 3-year study period for economic evaluations Calculate the incremental ROR, and identify the robot the manager should select The incremental ROR is % The manager should select robot (Click to select)
