Five workers assembled 200 tables      during an 8-hour shift. Workers are paid $10/hour and overhead cost is equal to the total labor cost.      The raw materials cost is $10 per table. If each table sells at $28, the multifactor productivity is ________ $ of revenue      per $ of input. 0.2 2.0 1.5 0.5 Solution Each worker is paid $80 for the whole day, so $400 for the day\'s cost. Overhead is equal to your total labor cost, for another $400. At $10 per table, total cost is $2000 + $400 + $400 = $2800. Revenue is $28 per table, a total of $5600. $5600/$2800 is $2 of revenue per $ of input. Cheers. .
