Q2 The market equilibrium price and quantity of a good may be found by solving the simultaneous equations: Q + 3P = 48 (1) Q – 2P = 30 (2) (a) Explain which of these equations represents the supply curve and which represents the demand curve. (b) If the demand curve were to be drawn with Q on the horizontal axis and P on the vertical axis, state the values of the slope and vertical intercept. (c) Determine the equilibrium price and quantity algebraically.

Include correctly labeled diagrams, if useful or required, in explaining your answers. A correctly labeled diagram must have all axes and curves clearly labeled and must show directional changes. If the question prompts you to “Calculate,” you must show how you arrived at your final answer.     Assume that sugar-based soft drinks are produced in a market shown on the graph above. Answer the following questions based on the information given in the graph. (a) To reduce the consumption of sugary soft drinks, suppose the government imposes a $2 per-unit sales tax on soft drinks. (i) Will the price of soft drinks increase by the full amount of the sales tax? Explain. (ii) Calculate the tax revenue the government can collect from the sale of soft drinks. Show your work. (iii) Will the consumer surplus increase, decrease, or stay the same after the tax? (iv) Calculate the deadweight loss created by the tax. Show your work.   (b) Suppose that instead of imposing the per-unit sales tax,…
