Question 9 2 pts A manager checked production records for the week and found that a worker produced 64 units of output in 40 hours. In the prior week, the same worker produced 78 units in 49 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) Question 10 2 pts A company has improved its production process. Under the old process, 11 workers could produce 4,914 units per hours and the materials cost $58 per unit of output. Workers are paid $15 per hour and the finished product is sold for $104 per unit. After the improvement, materials costs have been reduced by $14 per unit of output and it now takes 2 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)
