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.
