Price elasticity of demand is a measure of how sensitive the quantity demanded of a good or service is to changes in its price. It helps us understand the responsiveness of consumers to price changes.

To calculate the price elasticity of demand, we need to follow these steps:

1. Determine the initial price and quantity demanded: Start by identifying the initial price at which the good or service is being sold and the corresponding quantity demanded.

2. Determine the new price and quantity demanded: Next, determine the new price at which the good or service is being sold, and the corresponding quantity demanded at this new price.

3. Calculate the percentage change in price: Calculate the percentage change in price by subtracting the initial price from the new price, dividing it by the initial price, and multiplying by 100.

4. Calculate the percentage change in quantity demanded: Calculate the percentage change in quantity demanded by subtracting the initial quantity demanded from the new quantity demanded, dividing it by the initial quantity demanded, and multiplying by 100.

5. Calculate the price elasticity of demand: Divide the percentage change in quantity demanded by the percentage change in price. The result will give you the price elasticity of demand.

6. Interpret the price elasticity of demand: The value obtained from the calculation will determine the elasticity of demand. If the value is greater than 1, demand is considered elastic, meaning that a change in price will have a proportionally larger effect on quantity demanded. If the value is less than 1, demand is considered inelastic, indicating that a change in price will have a proportionally smaller effect on quantity demanded. If the value is exactly 1, demand is unitary elastic, meaning that a change in price will have an equal proportionate effect on quantity demanded.

Understanding the price elasticity of demand is crucial for businesses to make informed decisions about pricing strategies and to predict the impact of price changes on their sales.
