Answer:
1.5
Explanation:
Price elasticity of supply measures the responsiveness of quantity supplied to changes in price of the good.
Price elasticity of supply = midpoint change in quantity supplied / midpoint change in price
Midpoint change in quantity supplied = change in quantity supplied / average of both supply
change in quantity supplied = 300 - 100 = 200
average of both supply = (300 + 100) / 2 = 200
200 / 200 = 1
midpoint change in price = change in price / average of both price
change in price = $30 - $15 = $15
average of both price = ($30 + $15) / 2 = $22.50
15 / 22.5 = 0.67
1 / 0.67 = 1.5
If the absolute value of price elasticity is greater than one, it means supply is elastic. Elastic supply means that quantity supplied is sensitive to price changes.
