What does a mixed-market economy allow people to do?

open their own businesses
make economic choices
avoid any government regulation
disregard supply and demand

The correct answer is: "open their own businesses

".

In a mixed market economy, economic authorities implement income redistribution systems that reduce income inequalities and generate fairer outcomes for all the individuals that conform the society, if compared to the results that would be generated by the free interaction of economic agents in the markets (pure market economy situation).

Therefore, agents can choose their path (for example, open a business), but they do not lead the economy on their own, through their choices, because the effects of those choices are subsequently modified by the regulation of the goverment. Economic authorities keep an eye in the functioning of all markets and, therefore, on the forces of demand and supply.

open their own businesses

Explanation:

Mixed economy is a system in which the planned production methods operate simultaneously, when the state acts as a player - acting directly in production - but also the model of market production, when there is production conducted by the private initiative.

In a mixed economy, state production is driven by state-owned enterprises in strategic areas such as oil production. Private initiative operates in any area. In this way, we can say that in a mixed economy system people are allowed to open their own businesses, since this is no longer a prerogative of the State. Virtually all capitalist nations are to a greater or lesser extent mixed economies, since in addition to private action, the state operates in some sectors.
