Answer to Question 1

a) Percentage change in price = 200
Percentage change in quantity supplied = 10
Price elasticity of supply = 10/200 = 0.05
The good has a relatively inelastic supply.
b) Percentage change in price = -40
Percentage change in quantity supplied = -80
Price elasticity of supply = -80/-40 = 2
The good has a relatively elastic supply.

Answer to Question 2

B
