Answer to Question 1

D

Answer to Question 2

The income elasticity of demand = (percentage change in the quantity demanded)  (percentage change in income). Using the midpoint method to calculate the percentages, the percentage change in the quantity of meals demanded = (1.0 - 0.5 )  (0.75 )  100 = 66.67 percent and the percentage change in income (650 - 500 )  (575 )  100 = 26.1 percent. Therefore the income elasticity of demand equals (66.67 percent)  (26.1 percent) = 2.56.
