Suppose that the demand curve for corn has the equation p = -0.29q+6.265 and the supply curve for corn has the equation p = 0.2q +2.1, where p is the price per bushel in dollars and q is the quantity (demanded or produced) in billions of bushels. (a) Find the quantities supplied and demanded when the price of corn is $3.40 per bushel. (b) Determine the quantity of corn that will be produced and the price at which it will sell. (a) The quantity supplied when the price of corn is $3.40 is (Round to the nearest whole number as needed.) billion bushels.
Question #1: On the news there has been outrage over the price of Epipens, a medication needed for allergic reactions to food and bee stings. The price of a two-pack of Epipens has risen from $100 to $600. The number of Epipens purchased fell from 1000 to 400. At the current time, there are no substitutes for this drug Will this increase in price cause a decrease in demand or a decrease in quantity demanded? Illustrate your answer graphically (either by showing a movement along the demand curve or by shifting the demand curve).
