Answer:
B. gives the same answer regardless of the direction of change
Explanation:
The computation of the price elasticity of demand using mid point formula is shown below:
Price elasticity of demand = (Percentage change in quantity demanded) ÷ (percentage change in price)
where,
Percentage change in quantity demanded is
= (change in quantity demanded ÷ average of quantity demanded)
And,
The percentage change in price is
= (percentage change in price ÷ average of price)
Therefore, it reflects the same answer
