mework (Ch 04) The following graph shows the market for laptops in 2007. Between 2007 and 2008, the equilibrium price of laptops remained constant, but the equilibrium quantity of laptops increased. From this, you can conclude that between 2007 and 2008, the supply of laptops the demand for laptops Adjust the graph to illustrate your answer by showing the positions of the supply and demand curves in 2008. Note: Select and drag one or both of the curves to the desired position. Curves will snap into position, so if you try to move a curve and it snaps back to its original position, just drag it a little farther. PRICE (Dollars per laptop) QUANTITY (Laptops) Supply Demand Demand 0 and Supply
