Referring to Problem Great Southern Packing is considering replacing an equipment in the production line with a new one using cutting edge technology. The production level is expected to be increased to 800 boxes per shift. Labor cost will rise to $22 per hour per worker but only four works required in one shift. The material cost per box stays the same, and there is an overhead expense of $600 per 8-hour shift. 4. Compute the labor productivity, using boxes per labor hour as the measure. 5. Compute the labor productivity, using boxes per dollar labor cost as the measure. (round the number to two decimal places) 6. Compute the multifactor productivity. (round the number to two decimal places) 7. Compute the percentage of change in labor productivity (measure of boxes per dollar of labor cost) with production line change. (round the number to one decimal place) 8. Compute the percentage of change in multifactor productivity with production line change
