A more thorough explanation:

Definition: Exchange value refers to the amount of money that something can be exchanged for in a market or through a transaction. It is the monetary worth or price of something.

Example: If a person wants to sell their car, the exchange value would be the amount of money they can sell it for in the market. For instance, if the car is in good condition and the market demand is high, the exchange value would be higher compared to a car in poor condition with low market demand.

Another example is when a company wants to purchase raw materials from a supplier. The exchange value would be the amount of money the company is willing to pay for the raw materials, and the supplier is willing to accept for the transaction to take place.

These examples illustrate how exchange value is determined by the market demand and supply of a product or service, and how it can vary depending on the condition, quality, and availability of the item being exchanged.
