Answer:
works because prices serve as a means of communication between consumers and producers.
Explanation:
Market mechanism is the money is used as a medium of exchange between buyers and sellers in a open system of value (market).
In the market mechanism consumers are interested in maximising utility, while sellers want to maximise profit.
