To calculate the price elasticity of demand (PED), we use the formula:
\[ \text{PED} = \frac{\text{Percentage Change in Quantity Demanded}}{\text{Percentage Change in Price}} \]
Since I do not have access to the actual image or data from the supply and demand curve, I cannot compute the exact values for you. However, I can guide you on how to perform the calculation:
-
Determine the initial and new prices:
- Initial Price (P1) = $2.00
- New Price (P2) = $0.40
-
Calculate the percentage change in price: \[ \text{Percentage Change in Price} = \frac{P2 - P1}{P1} \times 100 = \frac{0.40 - 2.00}{2.00} \times 100 \]
-
Determine the initial and new quantities demanded: You would need to refer to the graph for the quantity demanded at these prices.
-
Calculate the percentage change in quantity demanded: \[ \text{Percentage Change in Quantity Demanded} = \frac{Q2 - Q1}{Q1} \times 100 \] Where Q1 is the initial quantity demanded and Q2 is the new quantity demanded.
-
Substitute these percentage changes into the PED formula to obtain the elasticity.
After you do these calculations, you can match the result to the options provided: 0.004, 0.2, 5, or 0.5 to find the correct answer.
