Assume that demand for a commodity Is represented by the equation P. 10 - .2Qd and supply by the equation P. 2+20+ , where Qd and Qs are quantity demanded and quantity supplied, respectively, and P is price. Using the equilibrium condition Qs , Qd , N Eq- 2 P. 2 +.2Qs , solve the equations to determine equilibrium price. Now determine equilibrium quantity. Graph the two equations to substantiate your answers
