Hello my name is Chase I hope your having a good day. Here's my Answer

Items that are used as money often have little value in and of themselves. For example, the paper used to print money is not particularly valuable. Money has value because it is an exchange medium that people understand and accept as such. When everyone accepts that a bill or a coin has value, people can use it as a form of payment to purchase goods or services. Before money existed, people used other systems to perform exchanges.

Bartering involves a direct trade for goods and services. Although some aspects of this transaction are similar to the exchange of money, bartering required time as people hammered out the terms of the deal. Utilizing money as the medium for trade simplified transactions significantly. Trade and barter were precursors to the monetary system used in today's society. Although trade and barter may seem almost archaic, they were the business solutions for people who lived before the convenience of credit card processing.
