WebTo determine the equilibrium price, do the following. Set quantity demanded equal to quantity supplied: Add 50P to both sides of the equation. You get. Add 100 to both sides of the equation. You get. Divide both sides of the equation by 200. You get P equals $2.00 per box. This is the equilibrium price. Web2 jan. 2024 · This example problem demonstrates how to find the equilibrium constant of a reaction from equilibrium concentrations of reactants and products.
