Now calculate the government's tax revenue if it sets a tax of $0, $20, $40, $50, $60, $80, or $100 per bottle. (Hint: To find the equilibrium quantity after the tax, adjust the “Quantity” field until the Tax equals the value of the per-unit tax.) Using the data you generate, plot a Laffer curve by using the green points (triangle symbol) to plot total tax revenue at each of those tax levels.
