=+a. How much tax revenue is the government collecting per month from my wife? Illustrate this as a vertical distance on your graph. (Hint: If you know how much she is consuming after the tax and how much in other consumption this leaves her with, and if you know how much in other consumption she would have had if she consumed that same quantity before the imposition of the tax, then the difference between these two “other consumption” quantities must be equal to how much she paid in tax.)
