Assume the market for spiral bound notebooks is in equilibrium. All students in public schools need notebooks of some type when they attend classes. For each of the following, explain the possible effects on demand and/or supply and equilibrium price and quantity of spiral bound notebooks using a correctly labeled supply and demand graph with equilibrium price and quantity labeled. Under your hand-drawn graph, list the determinant of supply and/or demand that causes each shift as well as the change in price and quantity.
