The market price of cheeseburgers in a college town decreased recently, and the students in an economics class are debating the cause of the price decrease. Some students suggest that the price decreased because several new burger joints have recently opened in the area. Other students attribute the decrease in the price of cheeseburgers to a recent increase in the price of french fries. Everyone agrees that the increase in the price of french fries was caused by a recent increase in the price of potatoes, which are not generally used in making cheeseburgers.

he first group of students thinks the decrease in the price of cheeseburgers is due to the fact that several new burger joints have recently opened in the area.

On the following graph, adjust the supply and demand curves to illustrate the first group's explanation for the decrease in the price of cheeseburgers.

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.

If the price decrease was large, then the supply shift in the market for cheeseburgers must have been larger than the demand shift. If the equilibrium quantity of cheeseburgers decreasesr then the supply shift in the market for cheeseburgers must have been larger than the demand shift. If the equilibrium quantity of cheeseburgers decreases, then me demand shift in the market for cheeseburgers must have been larger man the supply shift. Whichever change occurred rst must have been the primary cause of the change in the price of cheeseburgers
