Please help me understand the right steps. Thank you.

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 monthlyr market for champagne, which is shown on the following graph. Use the graph lnput tool to help you answer the following guestlons. You we'll not be graded on any changes you make to this graph. Note: Once you enter a value in a white eld, the graph and an'iur corresponding amounts in each greyeld will change accordingly.
