Which of the following is an example of barter?

• A. Paying with cash
• B. Using a credit card
• C. Trading a haircut for a ride
• D. Investing in stocks

Answer: (C)

Barter means exchanging goods or services directly without using money. Trading a haircut for a ride fits that definition because one person provides a haircut while the other provides a ride, and no cash or credit is involved. Each person gets something they want in return for something they offer, which is exactly how barter works. The other options involve money or financial systems: paying with cash uses currency; using a credit card relies on borrowing and paying later; investing in stocks involves putting money into assets. So this example shows a direct service-for-service swap without money, which is barter.
