Answer:
Economies of scale.
Step-by-step explanation:
In this scenario, the cost to manufacture one unit of Rinker Audio Products' bestselling hearing aid, the Magnifier, is $87.50. The chief financial officer (CFO) of the company, Neha Patel, has determined that if the company expands the output of its biggest U.S. plant by 20 percent, the unit cost would be only $82.50. The concept that as plant output expands, unit costs decrease, is known as economies of scale.
Economies of scale in microeconomics can be defined as cost reductions or cost advantages that arises when a business entity increases its level of production or are large in size.
This ultimately implies that, when a company chooses a convenient scale of operation or reduce its scale of production, this would lead to a reduction in the cost of production and consequently, some benefits such as lower long-run average cost, increased sales, profits and lower cost price for the consumers of these finished products.
