Figure: Determining Surplus and Loss) In the graph, if the government sets a maximum price of $5, there is a The graph plots Q against P and depicts an upward-sloping curve S and a downward-sloping curve D. The upward-sloping curve S extends from (2, 0) through (40, 8). The downward-sloping curve D extends from (16, 0) to a point on the horizontal axis through (40, 8). Three dashed lines parallel to the vertical axis start on the horizontal axis from 20, 40, and 60 and pass through the following points respectively: (20, 0), (20, 5), (20, 8), and extend beyond (20, 12). (40, 0), (40, 5), (40, 8), and extend beyond (40, 12). (60, 0), (60, 5), (60, 8), and extend beyond (60, 12). Three dashed lines parallel to the horizontal axis start on the vertical axis and pass through the following points respectively: (0, 12), (20, 12), (40, 12), and (60, 12). (0, 8), (20, 8), (40, 8), and extend beyond (60, 8). (0, 5), (20, 5), (40, 5), and (60, 5). The dashed lines intersect at (60, 5), (60, 8), (60, 12), (40, 5), (40, 8), (40, 12), (20, 5), (20, 8), and (20, 12) and form 9 rectangular plots. surplus of 20 units. shortage of 20 units. surplus of 40 units. shortage of 40 units.

(Figure: Bread and Honey) In the graph, a movement from point f to point g could occur if The graph plots honey against bread and depicts a concave down curve extending from (0, 90) through b (70, 75), and ending on the horizontal axis. Point b (70, 75) is on the curve, point a (30, 90) is outside the curve on the top left while point g is also outside the curve on the right. A rectangular plot connects (0, 0), (30, 0), a (30, 90), and (0, 90). The second rectangular plot connects (70, 0), (0, 0), b (70, 75), and (0, 75). people decide they prefer bread to honey. people decide they prefer honey to bread. unemployed workers find jobs. technological improvements occur.
