CHAPTER : Supply and Demand 59 /2. Consider the following supply and demand curves for a certain product. Us = 25,000P QD = 50,000 - 10,0001' a. Plot the demand and supply curves. b. What are the equilibrium price and equilibrium quantity for the industry: Determine the answer both algebraically and graphically. (Round to the nearest cent.) 3. The following relations describe the supply and demand for posters. QD = 65,000 - 10,0001 Qs = -35,000 + 15,000P where Q is the quantity and Pis the price of a poster, in dollars. a. Complete the following table. Price Qs Surplus or Shortage $6.00 5.00 4.00 3.00 1.00 b. What is the equilibrium price? The following relations describe monthly demand and supply for a computer support ser- vice catering to small businesses. QD = 3,000 - 10P Qs = -1,000 + 10P where Q is the number of businesses that need services and Pis the monthly fee, in dollars. a. At what average monthly fee would demand equal zero? b. At what average monthly fee would supply equal zero? c. Plot the supply and demand curves. d. What is the equilibrium price/ output level? e. Suppose demand increases and leads to a new demand curve: QD = 3,500 - 10P What is the effect on supply? What are the new equilibrium Pand Q? f. Suppose new suppliers enter the market due to the increase in demand so the new supply curve is Q=-500 + 10 P. What are the new equilibrium price and equilibrium quantity? g. Show these changes on the graph. 5. The ABC marketing consulting firm found that a particular brand of tablet PCs has the following demand curve for a certain region: Q = 10,000 - 200P + 0.03Pop + 0.61 + 0.2A where Q is the quantity per month, Pis price ($), Pop is population, / is disposable income per household (S), and A is advertising expenditure ($). a. Determine the demand curve for the company in a market in which P= 300, Pop = 1,000,000, 7 = 30,000, and A = 15,000. b. Calculate the quantity demanded at prices of $200, $175, $150, and $125. c. Calculate the price necessary to sell 45,000 units. ov's Frozen Yogurt shops have enjoyed rapid growth in northeastern states in recen
