Explanation:

A mixed economy combines elements of a pure socialists (command) economy and a  capitalist (free market )economy.  A socialist economy is where the government controls all economic activities and decisions in a country. The private sector is absent in a socialist economy.  A  capitalist or free-market economy is one where the government does not interfere with a country's economic activities. The private sector does production and distribution in the economy.
