Solo podrá vender lo que las personas están dispuestas a comprar a ese precio. De esta forma, si el precio que pone es muy alto, venderá pocas unidades mientras que si es bajo, venderá más unidades.

This question is incomplete, and I couldn't find its missing part online, but I can still assume that what you are giving is a definition and you need to find what it refers to.

Answer:

This definition refers to a monopoly.

Explanation:

A monopoly is a form of market where there is only one company that offers a product or service.

When this happens, only one company can offer this product or service since it has no close competition. This means that consumers who want said product or service can only go to this company and submit to the prices that it may impose.

The established price could be very high, but this could produce a low number of purchases by consumers. While if the price is low, consumers will be more.
