Suppose the price of Twinkies is reduced from $1.45 to $1.25 and, as a result, the quantity of Twinkies demanded increases from 2,000 to 2,200. Using the midpoint method, the price elasticity of demand for Twinkies in the given price range is
a. 2.00.
b. 1.55.
c. 1.00.
d. .64.

Price elasticity of demand measure the responsiveness of demand against change in the price of given product. It measures the ratio of change in demand to change in price.

Change in demand = ( 2200 - 2000 ) / [ (2200+2000)/2 ] = 200 / 2100 = 0.0952

Change in price = ( 1.25 - 1.45 ) / [ (1.25+1.45)/2 ] = 0.2 / 1.35 = 0.148

Elasticity of Demand = Change in demand / change in price = 0.0952 / 0.148 = 0.643 = 0.64
