downward-sloping straight line. A tax of $15 per unit is imposed on good X. The tax reduces the equilibrium

59. In the market for widgets, the supply curve is the typical upward-sloping straight line, and the demand curve is
the typical downward-sloping straight line. The equilibrium quantity in the market for widgets is 200 per
month when there is no tax. Then a tax of $5 per widget is imposed. As a result, the government is able to
raise $750 per month in tax revenue. We can conclude that the equilibrium quantity of widgets has fallen by
60. In the market for widgets, the supply curve is the typical upward-sloping straight line, and the demand curve is
the typical downward-sloping straight line. The equilibrium quantity in the market for widgets is 250 per
month when there is no tax. Then a tax of $6 per widget is imposed. As a result, the government is able to
raise $750 per month in tax revenue. We can conclude that the after-tax quantity of widgets is
