quivalently, to have -; that is, it must go from drag Increases, we must have MR > MC and then Mine this means Point 91 of maximum profit, the marginal-cost curve must cut the marginal-real . Hence, Find (a) we from below (Figure 13.67). For production up to 91, the revenue from adrills weight g "put would be greater than the cost of such output, and the total profit would incom output beyond 91, MC > MR, and each unit of output would add more to total in to total revenue. Hence, total profits would decline. 10. D to an in ied, p is price per 4. Fencing The owner of the Laurel Nursery Garden Center where e.
