What do supply and demand refer to in economics?

Supply and demand are fundamental concepts in economics that describe the relationship between the quantity of a good or service available in the market and the desire of consumers to purchase that good or service.

In this context, supply refers to the amount of a product that producers are willing and able to sell at various prices, while demand reflects consumers' willingness and ability to purchase that product at those prices. The interaction between supply and demand determines the market price of a product and influences how much of it is produced and sold. When demand for a product increases while supply remains constant, prices tend to rise. Conversely, if supply increases but demand remains steady, prices may fall.

The answer encompasses both the quantity of the product available for sale and the consumers' desire to buy, making it the most accurate representation of the supply and demand relationship.
