A "free market" refers to the basic system used to exchange goods or services - that is, it is really a micro-economic term. In a Free Market, you have buyers and sellers coming together, and mutually agreeing on a fair price without external dictation of that price A "free market economy" cover the entire economic system of the area, and, as such, takes into account not only private buyer/sellers, but government interaction. As such, it is a macro-economic term.
A FME uses the FM system as its basic building block, but can add varying degrees of government regulation on allowable economic activity. That is, price in FM exchanges are not dictated by the government in a FME, but which economic activities are allowable can be. Thus, in a FME, the government cannot dictate the price of anything, but it can dictate certain activities, such as allowable pollution, forbid certain contracts (e.g. Slavery), etc Once a government's involvement in a FME goes beyond mere regulation, into ownership of industry or infrastructure (which includes designation of allowed monopolies, even if they are private-owned) or establishment of programs of wealth transfer (generally, social welfare programs), the economy is now generally no longer considered a Free Market Economy, but is now a Mixed Market Economy.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest.
