The key difference between money and barter is that money is used as a medium of exchange to facilitate transactions, while barter involves the direct exchange of goods and services without a standardized intermediary.
In context to your responses, the most relevant points would be:
- "Money is used to exchange goods and services."
- "Money has value only because people agree that it has value."
These highlights illustrate that money serves as a universal medium of exchange and is based on collective agreement on its value, unlike barter, which requires a direct trade of items.
