Final answer:
Barter is the direct exchange of goods or services without money, posing challenges in modern economies, leading to the development of money.
Explanation:
Barter is the exchange of goods or services directly without using money as an intermediary. It involves trading goods that people directly value, as seen in informal arrangements like a mechanic repairing a caterer's truck in exchange for food.
In a barter system, exchanges require a double coincidence of wants, making it inefficient for modern economies with diverse job roles.
Early societies used bartering but later developed money as a means of exchange to avoid the limitations of direct exchange.
