Answer:
The multifactor productivity of the firm is 8 widgets per dollar
Explanation:
Total cost to produce 4,000 widgets = labor cost + material cost + overhead cost.
The Acme Widget Company produces the 4,000 widgets with the labor cost is $200, the material cost is $100, and the overhead cost runs $200.
Total cost to produce 4,000 widgets = $200 + $100 + $200 = $500
Cost per widget = $500/4,000 = $0.125
Number of widgets are produced per dollar = 1/$0.125 = 8 widgets
