Answer: D) inelastic.
Step-by-step explanation:
To find out the elasticity of the supply of corn, use the Price Elasticity of Supply (PES) formula. The price elasticity of supply shows how much quaintly supplied would change by if there was a change in price.
Price elasticity of supply = Change in quantity supplied / Change in price
= 20% / 30%
= 0.66
When the Price elasticity of supply is less than one, the supply is said to be inelastic. The PES here is less than 1 so corn is inelastic.
