Ask EduPadi AI for a detailed answer
Correct Option: B
To determine the elasticity of demand, we can use the following formula:
Price Elasticity of Demand (PED) = (% Change in Quantity Demanded) / (% Change in Price)
In this case:
1. **% Change in Price:** 8%
2. **% Change in Quantity Demanded:**
* Change in Quantity = 1492 - 1500 = -8 units
* % Change in Quantity = (-8 / 1500) * 100% = -0.53% (approximately)
Now, calculate the PED:
PED = -0.53% / 8% = -0.066
Interpreting the PED:
* If |PED| < 1
