Answer:
see below
Step-by-step explanation:
The law of diminishing marginal returns indicates that in every production process, adding one more input while holding the others constant will result in the overall decrease in output.
According to this law, adding one more production unit diminishes the marginal returns, and the average production cost increases. Marginal returns refer to the benefits associated with the production of an extra unit.
The gain derived from the use of more input while keeping all other factor constant decreases as production increases. For example, employing more workers while all other variables remain constant will result in reduced labor productivity.
