Answer:
It fulfilled the function of Exchange.
Step-by-step explanation:
When talking about money exchange, it refers to the exchange of money that is made for a service provided. In the past, this transfer was called barter, which was when a person had a product and was looking for another person who was interested in a said product to swap depending on what he wanted for making the exchange.
Now it is not necessary to look for a person who is willing to make a barter, if not that money is used to make the exchange of what is wanted, in this way the process is facilitated and no time is lost in the search.
Example of money exchange:
Paula goes to the supermarket because she needs eggs for breakfast, she pays the supermarket manager three dollars for the eggs she needs.
