Based on the information given the price elasticity of supply is 1.33.
Price elasticity of supply=(400,000-200,000)÷(200,000+400,000/2)÷(250-150)/(150+250/2)
Price elasticity of supply=(200,000)÷(600,000/2)÷(100)/(400/2)
Price elasticity of supply=(200,000÷300,000)÷(100/200)
Price elasticity of supply=0.6666/0.5
Price elasticity of supply=1.33
Inconclusion the price elasticity of supply is 1.33.
