Final answer:
The average sales per worker, or labor productivity, for U.S. apparel producers in 2010 cannot be determined without specific data. However, U.S. workers have generally increased their productivity over time.
Step-by-step explanation:
The average sales per worker, or labor productivity, for U.S. apparel producers in 2010 can be calculated by dividing the total sales by the number of workers. Unfortunately, the question does not provide the total sales or the number of workers, so it is not possible to give an exact answer. However, we can use the information provided in the reference to understand the concept of labor productivity.According to the information, the average amount produced by a U.S. worker in an hour was over $100 in 2011, which was more than twice the amount produced in 1966. This shows that U.S. workers have increased their productivity over time.Therefore, without specific data for U.S. apparel producers in 2010, we cannot determine the exact average sales per worker. However, we can infer that over time, U.S. workers have become more productive, which could also apply to the apparel industry.
