Assume that the demand curve D(p) given below is the market demand for widgets: Q=D(p)=1151?13pQ=D(p)=1151-13p, p > 0 Let the market supply of widgets be given by: Q=S(p)=?4+8pQ=S(p)=-4+8p, p > 0 where p is the price and Q is the quantity. The functions D(p) and S(p) give the number of widgets demanded and supplied at a given price.
