The market for paperback detective novels is perfectly competitive. Market Demand is given by Q=393-7P. Market Supply is given by Q=3P-9.
Suppose 55 units are bought to the market. Consider the Marginal Cost of production for these 55 units. What is the maximum Marginal Cost of production of these 55 units? Enter a number only, do not include the $ sign.
Hint: 55 doesn't have to be the market quantity.
Suppose the market price of sugar is 22 cents per pound. If a sugar farmer produces 100,000 pounds, the marginal cost of sugar is 30 cents per pound. Is the farmer maximizing profit? If not, should the farmer produce more or less sugar?
A firm’s marginal cost curve above the average variable cost curve is equal to the firm’s individual supply curve. This means that every time a firm receives a price from the market it will be willing to supply the amount of output where the price equals marginal cost. What happens to the firm’s individual supply curve if marginal costs increase?

- The market for drones is perfectly competitive. Assume for simplicity that fractions of everything, including firms, is possible. We have identical firms, each with a Total Cost curve of TC=257+g^2 and Marginal Cost curve MC=2q. Market demand is Q=797-2P. If the Fixed Cost increases by $10, what is the short-run market price?arrow_forwardThe market for drones is perfectly competitive. Assume for simplicity that fractions of everything, including firms, is possible. We have identical firms, each with a Total Cost curve of TC=334+q^2 and Marginal Cost curve MC=2a. Market demand is Q=807-2P. If the Marginal Cost for every firm decreases by $10 at every quantity, what is the short-run market price? (You can assume that MC>=AVC at every quantity for this question).arrow_forwardA perfectly competitive firm sells its good for $20. If marginal cost is four times the quantity produced, how much does the firm produce? Why? Assuming perfect competition, there is not enough information to determine how much the firm is producing. Assuming perfect competition, the firm is producing where MC is twice MR. If the price is $20, then MC is $40. This means that the firm is producing 10 units. Assuming perfect competition, the firm is producing where MR = MC. If the price is $20 and MC is four times the quantity, it is producing 80 units. Assuming perfect competition, the firm is producing where MR = MC = P. Since price is $20, MR is $20. If MC is 4 times the quantity, it is producing 5 units.arrow_forward
