a. Draw the supply and demand curves on the same diagram. Determine the equilibrium price and quantity and demonstrate it in your graph.

b. Demonstrate the impact of a government price control set at P = \$14. Demonstrate by number and in the graph. Discuss your answer.

c. Calculate the ARC elasticity of demand (midpoint formula) when the price moves from \$6 to \$2. Write the formula and show your work.

d. Redraw the Demand curve (only) in a new diagram. Demonstrate the Total Revenue change geometrically and indicate the Loss and Gain areas between the prices
of \$6 and \$2 (Price has moved UP from \$2 to \$6).

e. In this diagram as above (part d) demonstrate and calculate the Consumer Surplus when price is set at \$12 (P=12).

f. If for a product a 10% increase in consumer income leads to a 20% decrease in sale how would you evaluate the Income Elasticity of Demand? Is this a
Normal Good or an Inferior good? Calculate the Income elasticity of Demand first and then give your explanations for both questions.

g. If a 10% increase in the product such as Y leads to a 20% increase in the sale of Product X then what can you say about the Cross Elasticity of Demand for
X & Y? Are X & Y Substitutes or Complements? Calculate and Explain
