Handbook >> Market Equilibrium >> Using an EquationAlthough tables and graphs are very useful in representing the Market Equilibrium for a product, equations are sometimes used as well. Although many students try to avoid using equations, this is actually the easiest (and shortest) way to represent the Market Equilibrium for a product. For example, what if I wanted to know what the equilibrium price of red wine was? That is, the price where both consumers and producers would both sell and buy equal quantities. Getting the precise number from the table may be difficult. It would require extrapolating from the points that are there. On the other hand, if I gave you an equation it would be very easy.
