(15 pts) Assume that demand for a commodity is represented by the equation P=100.2Qd and supply by the equation P=2+0.2Qs, where quantity demanded and supplied is, respectively, Qd and Qs. Using the equilibrium condition Qs = Qd, solve the equations to determine equilibrium price and equilibrium quantity. Graph the two equations to substantiate your answers if the market prices are 2, 4, 6, 8, and 10. (25 pts) P' P -J - - - Supply Demand Q' Q Investopedia
