A t-shirt store in a monopolistically competitive market faces a demand curve for t-shirts given by P = 25 – 0.5Q (and so a marginal revenue of MR = 25 – Q). The variable costs of producing a t-shirt are VC = 3Q and so the marginal costs are constant at $3. If the t-shirt store is in a long-run equilibrium, what must its fixed costs be?

$242 ----- is correct
Profit is maximized at MR = MC
25 - Q = 3
Q= 22
P= 25 - 0.5*22= 14
Profit is 0 in long run equilibrium
Profit = PQ - VC - FC
0 = 14*22 - 3*22 - FC
FC = 242

4. Is monopolistic competition efficient? Suppose that a firm produces polo shirts in a monopolistically competitive market. The following graph shows its demand curve, marginal revenue (MR) curve, marginal cost (MC) curve, and average total cost (ATC) curve. Place a black point (plus symbol) on the graph to indicate the long-run monopolistically competitive equilibrium price and quantity for this firm. Next, place a grey point (star symbol) to indicate the minimum average total cost the firm faces and the quantity...

Suppose there is a monopolistically competitive market with n identical firms, such that each firm produces the same quantity, q. Further, the market is in the monopolistically competitive long-run equilibrium. You are given the following: Inverse market demand: P 10-Q Total market output: Qnxq Marginal revenue: MR 10n+ 1)xq Total cost: C(q)-5+q Marginal cost: MC 2xq In long-run equilibrium, each firm earns zero economic profit. In long-run equilibrium, the number of firms, n, is and each firm produces units) of...

(a) All firms in a perfectly competitive industry face the same long-run average cost curve, AC = 0.05q – 5 + 500/q, and the same long-run marginal cost curve given by MC = 0.1q – 5. The market demand for the product of these firms is QD = 100,000 – 10,000P. i.Calculate the equilibrium price and quantity. ii.Assuming the market is in long-run equilibrium, how many firms will be on the market? (b) Suppose the demand for cotton T-shirts is...
