Suppose the government imposes a $4-per-pack tax on suppliers. At this tax amount, the equilibrium quantity of cigarettes is packs, and the government collects in tax revenue. Now calculate the government's tax revenue if it sets a tax of $0, $4, $8, $10, 12, $16, or $20 per pack. (Hint: To find the equlibrium quantity after the tax, adjust the "Quantity" held 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. Note: Plot your points in the order in which you would like them connected. Line segments will connect the points automatically
