The supply curves are straight lines ascending to the right, and the demand curve is a straight line descending from upper left to lower right. S 1 is to the right of S 2. S 1 intersects Curve D at point (120, 9), and S 2 intersects Curve D at point (105, 12). Point (105, 8), is marked on S 1. Refer to Figure 6-13. Acme, Inc. is a seller of the good.
