Answer: 0.2
Explanation:
Elasticity of supply shows the responsiveness to the quantity supplied for a good or service to changes in market price. Supply is Elastic if its elasticity is greater than 1 and inelastic if elasticity is less than 1
Elasticity of supply = Percentage change in quantity supplied / Percentage change in Price
= 4%/ 20%
=0.2 which is inelastic.
