Answer:
-0.4725
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 Â
Midpoint change in quantity demanded = change in quantity demanded / average of both demands
change in quantity demanded = 180 - 200 = -20
average of both demands = (200 + 180 ) / 2 = 190
-20/190 = -0.105
midpoint change in price = change in price / average of both price
change in price = $5 - $4 = 1
Average of both price ($5 + $4) / 2 = $4.5
$1 / $4.5 = Â 0.222
-0.105 / Â 0.222 = -0.4725
If the absolute value of price elasticity is greater than one, it means demand is elastic. Elastic demand means that quantity demanded is sensitive to price changes. Â
Demand is inelastic if a small change in price has little or no effect on quantity demanded. The absolute value of elasticity would be less than one
Demand is unit elastic if a small change in price has an equal and proportionate effect on quantity demanded. Â
