Final answer:
Free-market economic systems primarily rely on prices to allocate resources and goods, using the forces of supply and demand to signal and guide producers and consumers.
Step-by-step explanation:
The economic system that primarily relies on prices for allocating resources and goods is the Free-market system. In this system, prices are determined by the forces of supply and demand, without any government intervention. These prices, in turn, guide producers to allocate resources efficiently, and they also signal consumers about the cost and value of goods and services. An example of a country that predominantly uses the free-market system is the United States, although it also includes certain mixed economy elements.
