Answer: Option (c) is correct.
Explanation:
Given that,
Price elasticity of demand = 0.5
Percentage increase in price = 8%
Price elasticity of demand = [tex]\frac{Percentage\ change\ in\ quantity\ demanded}{Percentage\ change\ in\ price}[/tex]
0.5 = [tex]\frac{Percentage\ change\ in\ quantity\ demanded}{8}[/tex]
Percentage change in quantity demanded = 0.5 × 8
= 4%
Therefore, if the price rises by 8% then as a result quantity demanded decreases by 4%.
