Answer:
D) 0.5
Explanation:
Elasticity of supply measures the degree of responsiveness of quantity supplied to changes in price.
Elasticity of supply = percentage change in quantity supplied / percentage change in price
10% / 20% = 0.5
A coefficient of 0.5 indicates supply is inelastic.
Inelastic supply means that the quantity supplied is less responsive to changes in price.
