Answer to Question 1

The higher price could have been brought about by an increase in demand, a decrease in supply, or the combination of an increase in demand combined with a decrease in supply. Hence the higher price could have been the result of a rightward shift in the demand curve, a leftward shift in the supply curve, or a combined rightward shift of the demand curve and leftward shift of the supply curve.

Answer to Question 2

The price elasticity of demand = (percentage change in the quantity demanded)  (percentage change in the price). Using the midpoint method to calculate the percentages, the percentage change in the quantity demanded = (700 - 500 )  (600 )  100 = 33.3 percent and the percentage change in the price is (10 - 14 )  (12 ) = -33.3 percent. We ignore the negative sign so that the price elasticity of demand equals (33.3 percent)  (33.3 percent), or 1.00.
