Price, dollars per pound Quantity, thousand pounds per day 1.90 1.35 1.5 2.2 1.25 1.20 0.95 4.4 5.9 6.5 0.85 0.73 7.0 8.8 Using the Excel trendline option to estimate a linear demand function, the linear demand function is Q= 12.53 – 6.25p. Suppose the quantity in the first row of the table were 3 instead of 1.5. The linear demand function would now be Q=-p. (Enter your responses rounded to two decimal places.) Suppose the quantity in the second row of the table were 3.2 instead of 2.2. The linear demand function would now be Q=-p. (Enter your responses rounded to two decimal places.)

The demand for product X depends on the price of product X as well as the average household income (Y) according to the following relationship Qdx=800-5P+0.001Y The supply of product X is positively related to own price of product X and negatively dependent upon W, the price of some input. This relationship is expressed as: Qsx= 100+ 45 P-4 W Given that Y = 50,000 and W= 4, what is the 1. Equilibrium price? Number 2. Equilibrium quantity? Number Suppose that income increases to 60,000 and W remains constant. What is the new: 3. Equilibrium price? Number 4. Equilibrium quantity? Number Assuming that income remains constant at 60,000 and W increases to 9, what is the new: 5: Equilibrium price? Number 6. Equilibrium quantity? Number

Q3. Refer to the diagram. Using the midpoint formula, calculate the price elasticity of demand between the prices of $15 and $12. Accordingly, state whether demand is elastic or inelastic between these two points. P$/unit 15 12 D 18 22 Q (units/week) Ep = Damand ie ... Q4. For each case below, answer the bolded questio Classification of the Case Calculations product(s) if requested to do so 1. Suppose that a 2% increase in income in the economy decreases the quantity of gadgets demanded by 1% ar every E,= Gadgets are possible price. Find the income elasticity of demand and dassify the product accordingly (state whether gadgets is a normal, necessity, luxury or an inferior product). 2. A firm finds that its price elasticity of demand is 4.0. Currently, the firm is selling 2000 units per month at $5 per unit. Price must be lowered by= If it wishes to increases its quantity sold by 10%, by how much it must lower its price? 1 Suppose legalization-and subseque nt regulation-of products Xand…
