A company has improved its production process. Under the old process, 11 workers could produce 4,810 units per hours and the materials cost $57 per unit of output. Workers are paid $18 per hour and the finished product is sold for $103 per unit. After the improvement, materials costs have been reduced by $12 per unit of output and it now takes 4 fewer workers to make the same amount of output. What is the percentage change in multifactor productivity? (do not use a % sign, e.g. enter 50% as .5) A manager checked production records for the week and found that a worker produced 53 units of output in 48 hours. In the prior week, the same worker produced 71 units in 32 hours. What is the percentage change in productivity for this worker? (enter in decimal format without a percent sign, e.g. 50% should be entered as.5)
