Susan Williams runs a small Flagstaff job shop where garments are made. The job shop employs eight workers. Each worker is paid $ 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 $ 90 each at a factory outlet store. The remaining 80 garments were sold to retail outlets at a price of $ 198 per garment. What was the labor productivity, in dollars per labor- hour, at this job shop during the first week of March?
