Most of the nations that broke away from the Soviet Union now have what type of economy? market mixed demand planned

The type of economy is Market

The correct answer is: "mixed"

A mixed economy combines both aspects from market and centrally-planned economic systems.

In a mixed economy, producers and consumers interact in the markets and determine through their choices the prices and the amounts exchanged of the different products, services and factors of production. But market outcomes are not considered efficient or fair in many situations, this is why economic authorities have power to intervene in the functioning of markets in order to introdce income redistribution policies, for example.
