\begin{tabular}{l} If 10 workers can produce 1,500 units of output and 11 workers can \\ produce 1,600 units of output, then the average product of 11 workers \\ is \\ OA) 1,600 units \\ \hline OB) 145.5 units \\ \hline OC) 136.4 units \\ \hline OD) 100 units \\ \hline\end{tabular}

To find the average product of the 11 workers, we divide the total output produced by the number of workers. With 11 workers producing 1,600 units of output, the average product is calculated as follows: Average Product = Total Output / Number of Workers = 1,600 units / 11 workers ≈ 145.45 units. So, the correct choice is OB) 145.5 units. Did you know that economic concepts like this one can be traced back to early agricultural societies? The idea of measuring productivity based on labor input has roots in how ancient communities allocated tasks to maximize crop yields, an essential skill for survival! As you dive deeper into production analysis, remember the common mistake of focusing solely on total output. It’s vital to understand that average product gives a clearer picture of efficiency per worker. Always compare with other metrics like marginal product for a holistic view!
