4. Elastic, inelastic, and unit-elastic demand The following graph shows the demand for a good. W 140 90 70 20 Demand 8 28 36 56 QUANTITY (Units) PRICE (Dollars per unit) N

Use the graph to answer the question that follows. What is the price elasticity of demand when price increases from $2 to $4? A-0.2 B-0.5 C-2 D-3 E-5

Price (dollars per pizza) 10 9 The data in the table above give two points on the demand curve for pizza. When the price of a pizza falls from $10 to $9, at the midpoint between these two prices what is the price elasticity of demand? 1. Calculate the Elasticity of Demand 2. Is the item Elastic, Unit Elastic, or Inelastic 3. Would you advise lowering the price? Explain Quantity demanded (pizzas per day) 100 125 Response should have the flowing format. 1. 2. 3.

m 18 of 21 > (Figure: The Demand for e-Books) Use Figure: The Demand for e-Books. What is the price elasticity of demand (by the midpoint method) when the price increases from $6 to $8? Figure: The Demand for eBooks Price $10 8 6 8+ 2.33 0.55 0.5 0.67 40 D 50 Quantity

Price ($) 0 1 2 3 4 5 6 7 8 Quantity 56 48 42 35 28 21 14 7 0 Instructions: Round intermediate calculations and round your answers to two decimal places. If you are entering a negative number be sure to include a negative sign (-) in front of that number. a. The price elasticity of demand for a price change from $2 to $3 is: -0.45 ✔ The slope of the demand curve for a price change from $2 to $3 is: b. The price elasticity of demand for a price change from $3 to $5 is: The slope of the demand curve for a price change from $3 to $5 is: c. The price elasticity of demand for a price change from $6 to $7 is: -7.00 -1.00 → -7.00 x -4.33 The slope of the demand curve for a price change from $6 to $7 is: -700

, From the following table, calculate elasticity of demand if you move from point A to C and explain what you understand from the result. Qy 220 POINT Px A 315 416 350 C 517 425

What is the primary determinant of the price elasticity of demand? A. The availability of substitutes B. The price level C. The income of consumers D. Government regulations

Q3 price Quantity demanded A 60 100 B 50 200 C 40 300 D 30 40 0 35 Quantity supplied 50 45 40 Use the information in the table above: a- Calculate the price elasticity of demand when the price changed from 50 to 60. b- Calculate the price elasticity of supply when the price changed from 40 to 30.
