Susan Williams runs a small Flagstaff job shop where garments are made. The job shop employs eight workers. Each worker dollar 10 per hour. During the first week of March, each worker worked 45 hours. Together, they produced a batch of 132 garments. Of these garments, 52 were "seconds" (meaning that they were flawed). The seconds were sold for dollar 90 each at a factory outlet store. The remaining 80 garments were sold to retail outlets at a price of dollar 198 per garment. What was the labor productivity, in dollars per labor-hour, at this job shop during the first week of March?
