Gracia Gilreath, Chapter 10, Question 6

I thought that the section that discussed bartering and the purpose of money was significant to why we use the currency we do. Before the American dollar was established people used to barter, or trade goods, in order to receive the item they needed, but this doesn't work very well in an advanced economy like the US, so the dollar was created. The dollar is viable because it serves as a means of exchange, it serves as a unit of account, it is portable and durable, and is relatively scarce so it is able to store value.
