9. Figure 6.16 shows a consumer demand curve for flour. Suppose the cost of turn-

ing wheat into flour is $0.20 per pound of retail-equivalent wheat. That is, the marketing bill for wheat made into flour is $0.20 per pound of retail-equivalent wheat. Draw in the wheat derived demand curve and label it DD. Next, suppose that the wheat supply curve is given by the formula P = $0.05 + 0.0005(Q), where Q is the pounds of retail-equivalent wheat. Draw this supply curve in the diagram and label it S^FARM. Then, clearly label the wheat farm price as P^F, the flour retail price as P^R, and the equilibrium quantity as Q^E.
