Answer to Question 1

a. The income elasticity of demand for good X = (3 / 3.5 ) / (20,000 / 40,000 ) = (0.8571 / 0.5 ) = 1.71. X is both a normal good and a luxury.
b. Since both income and Py change, you cannot calculate the income elasticity for good Y. The income elasticity can be measured if a change in income causes the quantity of Y purchased to change, holding everything else constant.

Answer to Question 2
