Define demand and quantity demanded. Quantity demanded is the amount a consumer is willing to buy at a single specified price. Damand is the relationship between quantity and price, showing a series of quantities consumers intend to buy at their respective prices. Demand also changes based on time and dimension. 2. Define supply and quantity supplied. Quantity supplied is the amount a seller is willing to offer at a single specified price. Supply is the relationship between quantity and price, showing quantities of a good sellers are willing to offer at a series of respective prices. 3. Use the following demand and supply schedules for sweatshirts below to answer questions in a through h. Price Quantity Demanded Quantity Supplied $60 0 2,400 $50 800 2,000 $40 1,600 1,600 $30 2,400 1,200 $20 3,200 800 $10 4,000 400 a. At a price of $10, what are the quantity demanded and the quantity supplied of sweatshirts? At $10 the quantity demanded will be 4,000 and the quantity supplied will be 400, creating a shortage. b. If the price increases to $20, what happens to the quantity demanded and the quantity supplied of sweatshirts?
2 At $20 the quantity demanded decreases to 3,200 and the quantity supplied increases to 800, still creating a shortage. c. If the price again increases to $30, what happens to demand and supply? Demand and supply will not be affected by a price increase. They are only affected by outside economic factors. d. What is the equilibrium price for sweatshirts? The equilibrium price is $40 where both quantity demanded, and quantity supplied are 1,600. e. What is the equilibrium quantity for sweatshirts? The equilibrium quantity is 1,600 sweatshirts. f. At $50, is there a shortage or surplus of sweatshirts? Of how many sweatshirts? At $50 the quantity demanded is 800 and the quantity supplied is 2,000, creating a surplus of 1,200 sweatshirts. g. There is a shortage of 1,200 sweatshirts at what price? At $30 where quantity demanded is 2,400 and quantity supplied is 1,200. h. No one will buy a sweatshirt for $_________ . 800 people will buy one for___. No one will buy a sweatshirt at $60. 800 people will buy one for $50. 4. Use the graph below related to the market schedule for slices of cheese pizza to answer questions in a through d. a. The market equilibrium price for cheese pizza is $_____ . $1.50 b. The equilibrium quantity of cheese pizza is ______ slices.
3 600 c. A surplus of 400 slices of cheese pizza exists at what price point? $___ . $2.00 d. If the price were set at $1, there would be a __________of _______slices. This would eventually cause prices to________. Shortage of slices that would cause prices to increase. 5. The initial demand and supply curves for beer per day are given by the following equations: Demand: Qd = 3,500 - 500P and Supply: Qs = 1,000P – 1,000, where Qd is the demand, Qs is the supply, and P is the price. a. Draw a graph (use the “Line” of the “Shapes” feature of MS Word 2010 under the “Insert” tab in the menu) of the demand and supply curves in this market clearly marking the values of vertical intercepts (i.e. value of price when quantity is zero) and horizontal intercepts (i.e. value of quantity when price is zero) on the graph (use the “Simple Text Box” of the “TextBox” feature of MS Word 2010 under the “Insert” tab in the menu). b. Use simple algebra to find equilibrium price and quantity traded and show them on the graph. c. Calculate the amount of the shortage at a price of $2. P=0 Qd = 3,500 -500(0) Qd = 3,500 Qs = 1,000(0) -1,000 Qs = 1,000 Qd = 0 0 = 3,500 -500p 500p = 3,500 P=7 Qs = 0 0 = 1,000p -1,000 1,000 = 1,000p 1 = p 2,500 1,000 2,000 $2 $3 -1,000 $1 3,500 $7 Qd = Qs 3,500 -500p = 1,000p -1,000 3,500 + 1,000 = 1,000p + 500p 4,500 = 1,500p 3 = p P = 3 Qs = 1,000(3) -1,000 Qs = 3,000 -1,000 Qs = 2,000 P = 3 Qd = 3,500 -500(3) Qd = 3,500 -1,500 Qd = 2,000 P = 2 Qs = 1,000(2) -1,000 Qs = 2,000 -1,000 Qs = 1,000 P = 2 Qd = 3,500 -500(2) Qd = 3,500 -1,000 Qd = 2,500
