Answer:
1
Step-by-step explanation:
Price elasticity of demand measures the responsiveness of quantity demanded to changes in price of the good.
Price elasticity of demand = percentage change in quantity demanded / percentage change in price
percentage change in quantity demanded = (452 - 62 / 452) - 1 = -0.137
percentage change in price = (54.58 / 48) - 1 = 0.137
=-0.137 / 0.137 = -1
-1 in absolute terms = 1
