Answer:
Option (C) is correct.
Explanation:
Elasticity of demand refers to the responsiveness of change in quantity demanded with any change in the price level.
Elasticity of demand:
= (change in quantity ÷ old quantity) ÷ (change in price ÷ old price)
=[(12 - 8) ÷ 8] ÷ [($3 - $2.25) ÷ $3]
= 0.5 ÷ 0.25
= 2
Therefore, the price elasticity of demand is 2.
