Final answer:
To calculate Price Elasticity of Demand, one must determine the percentage changes in quantity demanded and price, and then divide the former by the latter, considering the absolute value.
Step-by-step explanation:
The subject of the question is concerned with calculating the Price Elasticity of Demand (PED), which measures the responsiveness of the quantity demanded to a change in price. The PED can be calculated using a specific formula: PED = absolute value of (% change in quantity demanded / % change in price). To solve for PED using the provided information:
- First, calculate the percentage change in quantity demanded: ((300 - 500) / ((300 + 500) / 2)) x 100.
- Then, calculate the percentage change in price: ((11.50 - 10) / ((11.50 + 10) / 2)) x 100.
- Now calculate the PED: abs(percentage change in quantity / percentage change in price).
As the demand curve is typically downward sloping, PED is a negative value, but we consider it in absolute terms for practical purposes.
