What is the Law of Demand?

The Law of Demand is an economic principle that describes the inverse relationship between the price of a good or service and the quantity demanded by consumers. It states that as the price of a good or service increases, consumer demand for it decreases, and vice versa, assuming all other factors remain constant. This law illustrates the consumer behavior of purchasing less of a product when its price rises, and more when its price falls.

Example Calculation

Let's assume the following values:

Step 1: Calculate the quantity demanded:

\[ QD = 100 - (2 \cdot 10) = 100 - 20 = 80 \text{ units} \]

So, the quantity demanded is 80 units.
