Explanation:

An economic system is the method used by a society to produce and distribute goods and services.

-Traditional economies rely on the habit, custom, or ritual to decide what to produce, how to produce it, and to whom distribute it.

-In a centrally planned economy, the central government makes all decisions about the production and consumption of goods and services.

-In a market economy, economic decisions are made by individuals and are based on exchange, or trade.

-Mixed economies, are systems that combine tradition and the free market with limited government intervention.
