4. The Laffer curve
Government imposed taxes cause reductions in the activity that is being taxed, which has important implications for revenue collections.
To understand the effect of such a tax, consider the monthly market for champagne, which is shown on the following graph.
Use the graph input tool to help you answer the following questions. You will not be graded on any changes you make to this graph.
Note: Once you enter a value in a white field, the graph and any corresponding amounts in each grey field will change accordingly.

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.
