1. Understanding the point elasticity of demand Aa Aa Consider the demand for books shown on the following graph. PRICE (Dollars per book) 10 2 10 QUANTITY (Books per day) Fill in the following table with the slope of the demand curve at each of the given points. Recall that, because the demand curve is downward sloping, the slope should be reported as a negative number in each row. Price Point Quantity ($) Slope Point Elasticity Type of Elasticity A 3 B 8 Next, derive the point elasticity of demand at each of the points, and enter your result in the table. Round the point elasticity value to the nearest tenth. For example, if the correct answer is -1/3 for the point elasticity, enter "-.3" in the appropriate column. (Hint: The price elasticity of demand is the percentage change in quantity divided by the percentage change in price.) Then, fill in the last column by determining if the demand curve is elastic, unit elastic, or inelastic at each of the points. As you move along the demand curve from point C to point B, the demand curve gets elastic. True or False: The point elasticity of demand is equal to the slope of the demand curve. False True
