A company has introduced a processimprovement that reduces processing time for each unit, so thatoutput is increased by 25% with less material, but one additionalworker required. Under old process, five workers could produce60 units per hour. Labor costs are $12/hour, and materialinput was previously $16/unit. For the new process, materialis now$10/unit. Overhead is charged at 1.6 times direct laborcost. Finished units are sold for $31 each. What increase(or decrease) in productivity is associated with the process improvement?
(a) Productivity with old system
(b) Productivity with new system
(c) % change (increase or decrease) in productivity
