7. Use the graph below to answer the following questions: a. The interval elasticity of demand over the price range $3 to $5 is ______. b. The interval elasticity of demand over the price range $10 to $11 is ______. c. The interval elasticity of demand over the price range $5 to $7 is ______. 8. a. For the linear demand curve in problem 7, compute the price elasticity at each of the price points given in the following table. Make the elasticity calculations using the two alternative formulas, E = (∆Q/∆P) × (P/Q) and E = P/(P - A).

Consider the following data for a demand curve. Price: Quantity Demanded $3 80 $4 70 $5 60 $6 50 $7 40 $8 30 $9 20 $10 10 Fill in the blanks of the following statements using the midpoint formula. Between a price of $4 and $5, the price elasticity of demand is ____ (round to one decimal point) and at that point the demand elasticity is_____ . Between a price of $8 and $9, the price elasticity of demand is ____ (round to one decimal point) and at that point the demand elasticity is_____ . Revenue is maximized when the price is at $____ and the demand elasticity equals ____ .
