Answer:
25%
Step-by-step explanation:
Price elasticity of supply measures the responsiveness of quantity supplied to changes in price of the good.
Price elasticity of supply = percentage change in quantity supplied / percentage change in price
0.2 =5% / percentage change in price
percentage change in price = 5/0.2 = 25%
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.
Supply is inelastic if a small change in price has little or no effect on quantity supplied. The absolute value of elasticity would be less than one
Supply is unit elastic if a small change in price has an equal and proportionate effect on quantity supplied.
