1. Refer to the section on "Calculating the Price Elasticity of Demand". Review the formula for calculating price elasticity of demand and work out the following problem: A number of retail stores in San Diego form a "District". In that district, a popular brand of lady's handbag was selling at $400.00 per bag. In one week, the combined sale in the district was 200. The District Manager then declared a sale of 25% on the handbags. As a result, sale of the handbags increased to 550 in the following week. a. Calculate price elasticity of demand. (Use the following formula: Elasticity =(Change in quantity demanded/Average quantity)/(Change in pricelAverage price) b. What does the coefficient of elasticity indicate? Explain your answer. The price elasticity is positive and more than one. This means that it is elastic ( demand is sensitive to a price change)
