The opportunity cost measures the imposes a binding price ceiling on a competitive market, a shortage of the good arises, and according to the midpoint method, a change from $4 to $6 is considered a 40 percent rise complements. The cones are demanded and only 75 are supplied, so there is a shortage of 50 cones.
