For every price level given in the following table, use the graph to determine the profit-maximizing quantity of jumpsuits for the firm. Further, select whether the firm will choose to produce, shut down, or be indifferent between the two in the short run. (Assume that when price exactly equals average variable cost, the firm is indifferent between producing zero jumpsuits and the profit-maximizing quantity of jumpsuits.) Lastly, determine whether the firm will earn a profit, incur a loss, or break even at each price. Price (Dollars per jumpsuit) 15 20 25 55 70 85 Quantity (Jumpsuits) Produce or Shut Down? Profit or Loss?

On the following graph, use the orange points (square symbol) to plot points along the portion of the firm's short-run supply curve that corresponds to prices where there is positive output. (Note: You are given more points to plot than you need.)

Demand for microprocessors is given by P = 35 – 5Q , where Q is the quantity of microchips (in millions). The typical firm’s total cost of producing a chip is Ci = 5qi­, where qi is the output of firm i. a) Does the typical microchip firm display increasing, constant, or decreasing returns to scale? What would you expect about the real microchip industry? In general, what must be true about the underlying technology of production for competition to be viable?

The following graph plots the marginal cost (MC) curve, average total cost (ATC) curve, and average variable cost (AVC) curve for a firm operating in the competitive market for jumpsuits.

give everything in ms excel steps for the following (Profit Model) The demand for airline travel is quite sensitive to price. Typically, there is an inverse relationship between demand and price; when price decreases, demand increases and vice versa. One major airline has found that when the price (P) for a round trip between Chicago and Los Angeles is $500, the demand (D) is 700 passengers per day. When the price is reduced to $300, demand is 1,000 passengers per day. a. Plot these points on a coordinate system and develop a function that relates demand to price. b. Develop a mathematical model that will determine the total revenue as a function of price. c. Provide a recommendation to the airline company about the price that should be selected for the round trip between Chicago and Los Angeles such that their revenue is maximized. Describe how you have reached to this recommendation? (your solution may not be the best solution but should be a good solution).

Suppose that the tuna industry is in long-run equilibrium at a price of $5 per can of tuna and a quantity of 150 million cans per year. Suppose that the Centers for Disease Control (CDC) announces that a chemical found in tuna helps prevent many viral infections from spreading. The CDC's announcement will cause consumers to demand tuna at every price. In the short run, firms will respond by Shift the demand curve, the supply curve, or both on the following graph to illustrate these short-run effects of the CDC's announcement. 10 9.

Assume a firm's short-run cost function is given by the following expression: C(q) = 2+q+q² - If the firm can sell each unit of their output at a price of p maximizing level of output in the short-run? Profit maximizing q = dollars, what is the firm's profit

None

Consider the following total cost (TC) curve: 20 $/Q1 15 10. 5 5 MC 10 1 15 TC In the two graphs below, please (carefully) draw the marginal cost (MC) and the average variable cost (AVC) curves corresponding to the TC curve. Please identify the coordinates of the point on each curve at Q=3 (three) and Q = 15 (fifteen). That is, what is MC and AVC at Q=3 and = 15? Still, in other words, identify the coordinates of two points on each of the two curves. Output AVC
