After the bad start to the season and unexpected injuries, the Dallas Cowboys wants to sign 3 new players. There are five players under consideration. Player 1, 2 and 4 can play the quarterback position and Cowboys want to bring in at least one new player for this position. Each player has a strength given by sj, and Cowboys want to add at least S units of strength to the team by hiring some of these 5 players. On the other hand, the Cowboys will be careful while signing people who are prone to be penalties. Player j is likely to have at. penalties per season and Cowboys impose a quota of A penalties per season for these players. (a) If player j demands the salary cj, make up an IP to decide on which players should be signed to minimize the signing budget. (Just write out the IP) (b) If players 1 and 2 are buddies and will come to Dallas only together, add a constraint to guarantee that either they are signed together or they are not signed at all. (Just write this new constraint) (c) If player 1 hates player 3 and will not come if player 3 comes, add an appropriate constraint that does not allow signing player 1 and 3 together. (Just write this constraint)

5. profit maximization and shutting down in the short run suppose that the market for polos is a competitive market. the following graph shows the daily cost curves of a firm operating in this market. 0 2 4 6 8 10 12 14 16 18 20 50 45 40 35 30 25 20 15 10 5 0 price (dollars per polo) quantity (thousands of polos) mc atc avc for each price in the following table, calculate the firm's optimal quantity of units to produce, and determine the profit or loss if it produces at that quantity, using the data from the previous graph to identify its total variable cost. assume that if the firm is indifferent between producing and shutting down, it will produce. (hint: you can select the purple points [diamond symbols] on the previous graph to see precise information on average variable cost.) price quantity total revenue fixed cost variable cost profit (dollars per polo) (polos) (dollars) (dollars) (dollars) (dollars) 12.50 135,000 27.50 135,000 45.00 135,000 if the firm shuts down, it must incur its fixed costs (fc) in the short run. in this case, the firm's fixed cost is $135,000 per day. in other words, if it shuts down, the firm would suffer losses of $135,000 per day until its fixed costs end (such as the expiration of a building lease). this firm's shutdown price—that is, the price below which it is optimal for the firm to shut down—is per polo.
