A company that makes shopping carts for supermarkets and other stores recently purchased some new equipment that reduces the labor content of the jobs needed to produce the shopping carts. Prior to buying the new equipment, the company used 6 workers, who together produced an average of 60 carts per hour. Workers receive $17 per hour, and machine cost was $50 per hour. Compute the multifactor productivity. Use carts per dollar cost (labor plus equipment) as the measure. (Round your answers to 3 decimal places.)
