2: Question Content AreaEffects of Tax Figure 1: A graph shows an upward sloping Supply curve and a downward sloping Demand curve plotting the relationship between Quantity on the horizontal axis and Price on the vertical axis. Quantity ranges from 0 to 24 in increments of 2. Price ranges from 0 to 100 in increments of 10. The Supply curve starts from point (0, 2), passes through points Z at (40, 6), (60, 8), and ends at the top right. The Demand curve starts from point (0, 20), passes through a point Y at (40, 12), intersects the Supply curve at (60, 8), and ends at the point (100, 0). Horizontal and vertical drop lines extend from points Y on the Demand curve, intersection point (60, 8), and Z on the Supply curve. Refer to the figure. The imposition of the tax causes the quantity sold to _______. a. increase by 20 units b. decrease by 6 units c. decrease by 20 units d. increase by 6 units
