Figure 1 The vertical distance between points A and B represents a tax in the market. Price 12- 11 10 Supply Demand 0.5 4.5 Quantity 1. Refer to Figure 1: The imposition of the tax causes the quantity sold to A) increase by 1 unit. B) decrease by 1 unit. C) increase by 2 units. D) decrease by 2 units. 2. Refer to Figure 1: The amount of tax revenue received by the government is A) $2.50. B) $4. C) $5. D) $9. 3. For good X, the supply curve is the typical upward-sloping line, and the demand curve is the typical downward-sloping straight line. A tax of $15 per unit is imposed on good X. The tax reduces the equilibrium quantity in the market by 300 units. The deadweight loss from the tax is A) $1750 B) $2250 C) $3000 D) 45000 4. 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.
