Answer:
0.54
Explanation:
Price elasticity of demand measures the responsiveness of quantity demanded to changes in price of the good.
Price elasticity of demand = midpoint change in quantity demanded / midpoint change in price
Midpoint change in quantity demanded = change in quantity demanded / average of both demands
change in quantity demanded = 100 - 95 = 5
average of both demands = (100 + 95) / 2 = 97.5
Midpoint change in quantity demanded = 5 / 97.5 = 0.051282
midpoint change in price = change in price / average of both price
change in price = $11 - $10 = 1
average of both price = ($11 + $10) / 2 = 10.5
midpoint change in price = 1 / 10.5 = 0.095238
Price elasticity of demand = 0.051282 / 0.095238 = 0.54
