Market Demand (D) and Supply (S) functions are, respectively: Demand (D): P = 58 - 1.5Q, Supply (S): P = 12 + 2Q. (1) Graph D and S in the same diagram with P on the vertical axis and Q on the horizontal. In turn, compute the equilibrium price (Pe), the equilibrium quantity (Qe) and Net Benefits at Qe (NBe). (2) Show that Net Benefits at Q = 8 (NB:) are less than NBe. (3) Show that Net Benefits at Q = 20 (NB20) are less than NBe
