Answer:
Law of increasing costs.
Step-by-step explanation:
The law of increasing costs is a rule in economic science, according to which with increasing production of the product the opportunity costs also increase, that is, with the production of each new unit of product, the costs of producing this additional unit of product also increase.
Opportunity costs are the number of products that must be sacrificed in the production of any quantity of other products. And the law of increasing costs states that the production of an additional unit of product 1 leads to an increase in the number of refusals to produce product 2.
