Refer to the diagram given below. The diagram has two panels. (a) and (D). $40.000 37,000 $37,000 DH 35,000 DM D. 900 700 900 1 150 Cars per week Cars per week (a) Flexible price (b) Fixed price Panel (a) represents the demand for and the supply of a brand of automobile (Turbo car) for Fancy Auto, a car manufacturing company. Assume that DL represents the demand for Turbo cars when demand is low, DM represents the demand for Turbo cars when demand is medium, and DH represents the demand for Turbo cars when demand is high. If Fancy Auto's optimal output level is 900 cars per week and the price of Turbo cars is flexible, Fancy Auto:Multiple Choice O can continue to sell its optimal output regardless of the demand level. O can produce at its optimal output level only if the level of demand is at DM. O can sell more than its optimal output when the level of demand is DH. O can produce at its optimal output level only if the level of demand is DL
