a)Consider a demand curve of the form Qd = 20-2p where Qd is the quantity demanded of a good and p is the price of the good. Also consider a supply curve of the form Qs = 2p-4 where Qs is the quantity supplied. Graph these curves. At what values of P and Q do these curves intersect? b) Now suppose at each price individuals demand four more units of output, that is the demand curve shifts to Qd = 24-2p. Graph this new curves. Graph this new curve on the diagram drawn in part a) At what values of P and Q does the new demand curve intersect the supply curve identified in part a)
