0

B.

0.5

C.

1

D.

5

Correct answer is C

The price elasticity of supply = % change in quantity supplied / % change in price. When calculating the price elasticity of supply, economists determine whether the quantity supplied of a good is elastic or inelastic.

change in price = 10 - 15 = 5
change in quantity = 10 - 15 = 5
5 ÷ 5 = 1
