Marcus Tube, a manufacturer of high-quality aluminum tubing, has maintained stable sales and profits over the past 10 years. Although the market for aluminum tubing has been expanding by 3 % per year, Marcus has been unsuccessful in sharing this growth. To increase its sales, the firm is considering an aggressive marketing campaign that centers on regularly running ads in all relevant trade journals and exhibiting products at all major regional and national trade shows. The campaign is expected to require an annual tax-deductible expenditure of $ 155 comma 000 over the next 5 years. Sales revenue, as shown in the income statement for 2018 LOADING..., totaled $ 20 comma 800 comma 000. If the proposed marketing campaign is not initiated, sales are expected to remain at this level in each of the next 5 years, 2019 through 2023. With the marketing campaign, sales are expected to rise to the levels shown in the table LOADING... for each of the next 5 years; cost of goods sold is expected to remain at 73 % of sales; general and administrative expense (exclusive of any marketing campaign outlays) is expected to remain at 9 % of sales; and annual depreciation expense is expected to remain at $ 500 comma 000. Assuming a 40 % tax rate, find the net cash flows over the next 5 years associated with the proposed marketing campaign.

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.

Problem page a medical equipment industry manufactures x-ray machines. the unit cost c (the cost in dollars to make each x-ray machine) depends on the number of machines made. if x machines are made, then the unit cost is given by the function =cx+−0.3x2126x31,935 . how many machines must be made to minimize the unit cost?
