Suppose that annual demand in the U.S. market for ice cream cones can be expressed as QD = 800 + .2I - 100P, where QD is the number of cones demanded in millions of cones, I equals average monthly income in dollars, and P is price in dollars per cone. Supply can be expressed as QS = 200 + 150P (with the same units for quantity and price). A. Graph the demand and supply curves for ice cream cones, assuming that average monthly income is $2,000, and solve for the equilibrium price and quantity. B.

How shifts in demand and supply affect equilibrium Consider the market for pens. Suppose that the number of students with an allergy to pencil erasers increases, causing more students to switch from pencils to pens in school. Moreover, the price of plastic, an important input in pen production, has dropped considerably. On the following graph, labeled Scenario 1, indicate the effect these two events have on the demand for and supply of pens. 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.arrow_forwardThe price of oil is currently over $80 per barrel and has been as high as $90 per barrel after Saudi Arabia and a couple of oter OPEC countries reduced output this year.
