1. Understanding Supply Elasticity of Supply
Suppose the percentage change in quantity supplied is 0% when the price increases. What is the elasticity of supply? Draw a supply curve that accurately represents this elasticity of supply.
1. Using the information in the table, find the elasticity of supply when the price rises from $50 to$60. Is it inelastic, or elastic? Does the supply curve intersect the origin?
