Hand written solutions are strictly prohibited
Now calculate the government's tax revenue if it sets a tax of $0, $10, $20, $25, $30, $40, or $50 per case. (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.
Note: Plot your points in the order in which you would like them connected. Line segments will connect the points automatically.

Suppose the government is currently imposing a $15-per-case tax on champagne.

True or False: The government can raise its tax revenue by increasing the per-unit tax on champagne.

On the following graph, use the black curve (plus symbols) to illustrate the deadweight loss in these cases. (Hint: Remember that the area of a
triangle is equal tox Base x Height. In the case of a deadweight loss triangle found on the graph input tool, the base is the amount of the tax
and the height is the reduction in quantity caused by the tax.)
