Bartering involves exchanging goods and services. But today, _________can be exchanged for goods and services. A)money B)cost C) price
The correct answer is But today, money can be exchanged for goods and services
Explanation:
Bartering was a basic economic system in which individuals exchanged one product or service for another. For example, you can exchange a pound of rice for one of fruit. This was used in early communities before money was invented; however, nowadays bartering is not common in modern societies. This is because there is money or representations of it such as checks, credit cards, etc. and this is used to get goods and services. This means, today, it is money rather than other products the item use to obtain goods and services.
