2.) Production, Inputs, and Cost: Building Blocks for Supply Analysis First, use the following schedule to calculate the marginal revenue, the marginal cost, the total profit, and the marginal profit. Then, list the formula for total revenue and total cost. Lastly, discuss the condition under which the firm will earn a profit, incur a loss, the output that maximizes the perfectly competitive firm's profit, and under which a firm is maximizing profit by minimizing loss.

7. Short-run supply and long-run equilibrium Consider the competitive market for copper. Assume that, regardless of how many firms are in the industry, every firm in the industry is identical and faces the marginal cost (MC), average total cost (ATC), and average variable cost (AVC) curves shown on the following graph.

6. Deriving the short-run supply curve Consider the competitive market for dress shirts. The following graph shows the marginal cost (MC), average total cost (ATC), and average variable cost (AVC) curves for a typical firm in the industry. COSTS (Dollars) PRICE (Dollars per shirt) 100 90 80 70 60 50 100 40 90 10 80 0 70 Price (Dollars per shirt) 60 50 20 10 0 0 For each price in the following table, use the graph to determine the number of shirts this firm would produce in order to maximize its profit. Assume that when the price is exactly equal to the average variable cost, the firm is indifferent between producing zero shirts and the profit- maximizing quantity. Also, indicate whether the firm will produce, shut down, or be indifferent between the two in the short run. Lastly, determine whether it will make a profit, suffer a loss, or break even at each price. 15 20 25 55 70 85 10 0 0 0 MC D ATC On the following graph, use the orange points (square symbol) to plot points along the…
3. Profit maximization using total cost and total revenue curves Suppose Madison operates a handicraft pop-up retail shop that sells phone cases. Assume a perfectly competitive market structure for phone cases with a market price equal to $25 per phone case. The following graph shows Madison's total cost curve. Use the blue points (circle symbol) to plot total revenue and the green points (triangle symbol) to plot profit for phone cases for quantities zero through seven (including zero and seven) that Madison produces. TOTAL COST AND REVENUE (Dollars) 200 175 150 125 100 75 50 0 * U 0 1 O 2 n D 0 3 QUANTITY (Phone cases) ■ Total Cost O Total Revenue Profit Calculate Madison's marginal revenue and marginal cost for the first seven phone cases they produce, and plot them on the following graph. Use the blue points (circle symbol) to plot marginal revenue and the orange points (square symbol) to plot marginal cost at each quantity.
