Juanita is deciding whether to buy a dress that she wants, as well as where to buy it. three stores carry the same dress, but it is more convenient for juanita to get to some stores than others. for example, she can go to her local store, located 15 minutes away from where she works, and pay a marked-up price of $100 for the dress:
store
travel time each way
price of a dress
(minutes)
(dollars per dress)
local department store 15 100
across town 30 86
neighboring city 60 63
juanita makes $56 an hour at work. she has to take time off work to purchase her dress, so each hour away from work costs her $56 in lost income. assume that returning to work takes juanita the same amount of time as getting to a store and that it takes her 30 minutes to shop. as you answer the following questions, ignore the cost of gasoline and depreciation of her car when traveling.
complete the following table by computing the opportunity cost of juanita's time and the total cost of shopping at each location.
store
opportunity cost of time (dollars)
price of a dress (dollars per dress)
total cost (dollars)
local department store ? 100 ?
across town ? 86 ?
neighboring city ? 63 ?
assume that juanita takes opportunity costs and the price of the dress into consideration when she shops. juanita will minimize the cost of the dress if she buys it from the __

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.
