Answer :
The number of tools or machines each worker has to work with measures the b) capital per worker ratio.
This concept is crucial to understanding the productivity of workers. Productivity growth is closely linked to the average level of wages as well as the overall effectiveness of an economy for producing output.
Essentially, as productivity increases due to better tools, machines, or methods, the value of output each worker can generate also rises.
Despite this, wages of individual workers are influenced by a variety of factors, including the labor market and the nature of their tasks, and may not directly correspond to the tools or capital they use.
In an economic framework, capital per worker helps to estimate productivity and predict potential for economic growth.
