Assume the demand for a companys drug Wozac during the current year is 50,000, and assume demand will grow at 5% a year. If the company builds a plant that can produce x units of Wozac per year, it will cost 16x. Each unit of Wozac is sold for 3. Each unit of Wozac produced incurs a variable production cost of 0.20. It costs 0.40 per year to operate a unit of capacity. Determine how large a Wozac plant the company should build to maximize its expected profit over the next 10 years.
It costs a pharmaceutical company 75,000 to produce a 1000-pound batch of a drug. The average yield from a batch is unknown but the best case is 90% yield (that is, 900 pounds of good drug will be produced), the most likely case is 85% yield, and the worst case is 70% yield. The annual demand for the drug is unknown, with the best case being 20,000 pounds, the most likely case 17,500 pounds, and the worst case 10,000 pounds. The drug sells for 125 per pound and leftover amounts of the drug can be sold for 30 per pound. To maximize annual expected profit, how many batches of the drug should the company produce? You can assume that it will produce the batches only once, before demand for the drug is known.
Lemingtons is trying to determine how many Jean Hudson dresses to order for the spring season. Demand for the dresses is assumed to follow a normal distribution with mean 400 and standard deviation 100. The contract between Jean Hudson and Lemingtons works as follows. At the beginning of the season, Lemingtons reserves x units of capacity. Lemingtons must take delivery for at least 0.8x dresses and can, if desired, take delivery on up to x dresses. Each dress sells for 160 and Hudson charges 50 per dress. If Lemingtons does not take delivery on all x dresses, it owes Hudson a 5 penalty for each unit of reserved capacity that is unused. For example, if Lemingtons orders 450 dresses and demand is for 400 dresses, Lemingtons will receive 400 dresses and owe Jean 400(50) + 50(5). How many units of capacity should Lemingtons reserve to maximize its expected profit?
If a monopolist produces q units, she can charge 400 4q dollars per unit. The variable cost is 60 per unit. a. How can the monopolist maximize her profit? b. If the monopolist must pay a sales tax of 5% of the selling price per unit, will she increase or decrease production (relative to the situation with no sales tax)? c. Continuing part b, use SolverTable to see how a change in the sales tax affects the optimal solution. Let the sales tax vary from 0% to 8% in increments of 0.5%.
An electronics firm is currently manufacturing an item that has a variable cost of $0.50 per unit and a selling price of $1.10 per unit. Fixed costs are $15,000. Current volume is 30,000 units. The firm can substantially improve the product quality by adding a new piece of equipment at an additional fixed cost of $5,600. Variable cost would increase to $0.65 and the selling price would be revised to $1.30 with the expectation that the volume would be 50,000 units as a result of a higher-quality product. If the firm does not add new equipment, its profit will be =_____ dollars (round your response to the nearest whole number and include a minus sign if the profit is negative).
At modern woodworks, president and producer of apple crates sold to growers, has been able, with his current equipment, to produce 240 crates per 100 logs. He currently purchases 100 logs per day, and each log requires 3 labor hours to process. He believes that he can hire a profesional buyer who can buy a better quality log at the same cost. if this is the case, he can increase hos production to 260 crates per 100 logs. His labour-hours will increase by 8 hours per day. What will be the impact on productivity (measured in crates per labor-hour) if the buyer is hired?
Patz Company produces two types of machine parts: Part A and Part B, with unit contribution margins of $400 and $800, respectively. Assume initially that Patz can sell all that is produced of either component. Part A requires two hours of assembly, and B requires five hours of assembly. The firm has 400 assembly hours per week. What if market conditions are such that Patz can sell at most 100 units of Part A and 80 units of Part B? Express the objective function with its associated constraints for this case.

A plant operation has a fixed costs of $2,000,000 per year and its output capacity is 100,000 electrical appliances per year. The variable cost is $40 per unit and the product sells for $90 per unit. Compare annual profit when the plant is operating at 90% of capacity with the plant operation at 100% capacity. Assume that the first 90% of capacity output is sold at $90 per unit and that the remaining 10% of production is sold at $70 per unit.
The Electrocomp Corporation manufactures two electrical products: air conditioners and large fans. The assembly process for each is similar in that both rquire a certain amount of wiring and drilling. Each air condtioner takes 3 hours of wiring and 2 hours of drilling. During the next production period, 240 hours of wiring time are available, and up to 140 hours of drilling time may be used. Each air conditioner sold yieds a profit of $25. Each fan assembled may be sold for a $15 profit. Formulate the best combination of air conditioners and fans that yiedls the highest profit. Use the corner point graphical approach.
each company sinks wells of the same size at the same time. If both companies sink wide wells, each will extract 2 million barrels in 6 months, but each company will receive profit of only GHC 1 million. On the other if each company sinks a narrow well, it will take a year for Clampett and TEXplor to extract their respective shares, but their profits will be GHC14 million apiece. Finally, if one company drills a wide well while the other company drills a narrow well, the first company will extract 3 million barrels and the second company will extract only 1 million barrels. In this case, the first company will earn profits of GHC 16 million and the second company will actually lose GHC 1million.1. Illustrate this using a normal form game. 2. Does either firm have a strictly dominant strategy? If yes, what is (are) these strategies? Explain your answer. 3. What strategy will each firm adopt? Explain your answer. 4.

PROBLEM The management of the Book Warehouse Company wishes to apply the Miller-Orr model to manage its cash investment. They have determined that the cost of either investing in or selling marketable securities is $100. By looking at Book Warehouse’s past cash needs, they have determined that the variance of daily cash flows is $20,000. Book Warehouse’s opportunity cost of cash, per day, is estimated to be 0.03%. Based on experience, management has determined that the cash balance should never fall below $10,000. 1. How much is the cost per transaction?(Use a number, no decimal value, no commas, no currency, no space) * 2. How much is the return point based on the Miller-Orr model of cash management? (Use a number, no decimal value, no commas, no currency, no space) * 3. How much is the upper limit based on the Miller-Orr model of cash management?(Use a number, no decimal value, no commas, no currency, no space) * PLEASE ANSWER ALL QUESTIONS. THANKS!
