1. This year the Druehl, Inc., will produce 57,600 hot water heaters at its plant in Delaware, in order to meet expected global demand. To accomplish this, each laborer will work 160 hours per month. If the labor productivity at the plant is 0.15 hot water heaters per labor-hour, how many laborers are employed to the plant.
2. As part of the Department of Labor Statistics, you are assigned the task of evaluating the improvement in productivity of small businesses. Data for one of the small businesses you are to evaluate is shown below. The data is the monthly average of the last year and the monthly average of this year. Determine the multifactor productivity with dollars as the common denominator for:
a) Last year.
b) This year.
c) Then determine the percentage change in multifactor productivity for the monthly average last year versus the monthly average this year.
