Supply and demand equations

WebGenerally, though, these equations are represented as functions of the price. The equilibrium point is the point at which they're equivalent, Q_s = Q_d Qs = Qd. 10 \sqrt {300} 300 5 300 0 For a given product, suppose that the formula for supply is Q_s=2p^2 Qs = 2p2 and the formula for demand is Q_d=300-p^2 Qd = 300−p2. What's the equilibrium point? WebThe price elasticity of supply is the percentage change in quantity supplied divided by the percentage change in price. Elasticities can be usefully divided into five broad categories: …
