Scenario 3 Ben Gibson, the purchasing manager at Coastal Products, was reviewing purchasing expenditures for packaging materials with Jeff Joyner. Ben was particularly disturbed about the amount spent on corrugated boxes purchased from Southeastern Corrugated. Ben said, I dont like the salesman from that company. He comes around here acting like he owns the place. He loves to tell us about his fancy car, house, and vacations. It seems to me he must be making too much money off of us! Jeff responded that he heard Southeastern Corrugated was going to ask for a price increase to cover the rising costs of raw material paper stock. Jeff further stated that Southeastern would probably ask for more than what was justified simply from rising paper stock costs. After the meeting, Ben decided he had heard enough. After all, he prided himself on being a results-oriented manager. There was no way he was going to allow that salesman to keep taking advantage of Coastal Products. Ben called Jeff and told him it was time to rebid the corrugated contract before Southeastern came in with a price increase request. Who did Jeff know that might be interested in the business? Jeff replied he had several companies in mind to include in the bidding process. These companies would surely come in at a lower price, partly because they used lower-grade boxes that would probably work well enough in Coastal Products process. Jeff also explained that these suppliers were not serious contenders for the business. Their purpose was to create competition with the bids. Ben told Jeff to make sure that Southeastern was well aware that these new suppliers were bidding on the contract. He also said to make sure the suppliers knew that price was going to be the determining factor in this quote, because he considered corrugated boxes to be a standard industry item. Is Ben Gibson acting legally? Is he acting ethically? Why or why not?

The Tinkan Company produces one-pound cans for the Canadian salmon industry. Each year the salmon spawn during a 24-hour period and must be canned immediately. Tinkan has the following agreement with the salmon industry. The company can deliver as many cans as it chooses. Then the salmon are caught. For each can by which Tinkan falls short of the salmon industrys needs, the company pays the industry a 2 penalty. Cans cost Tinkan 1 to produce and are sold by Tinkan for 2 per can. If any cans are left over, they are returned to Tinkan and the company reimburses the industry 2 for each extra can. These extra cans are put in storage for next year. Each year a can is held in storage, a carrying cost equal to 20% of the cans production cost is incurred. It is well known that the number of salmon harvested during a year is strongly related to the number of salmon harvested the previous year. In fact, using past data, Tinkan estimates that the harvest size in year t, Ht (measured in the number of cans required), is related to the harvest size in the previous year, Ht1, by the equation Ht = Ht1et where et is normally distributed with mean 1.02 and standard deviation 0.10. Tinkan plans to use the following production strategy. For some value of x, it produces enough cans at the beginning of year t to bring its inventory up to x+Ht, where Ht is the predicted harvest size in year t. Then it delivers these cans to the salmon industry. For example, if it uses x = 100,000, the predicted harvest size is 500,000 cans, and 80,000 cans are already in inventory, then Tinkan produces and delivers 520,000 cans. Given that the harvest size for the previous year was 550,000 cans, use simulation to help Tinkan develop a production strategy that maximizes its expected profit over the next 20 years. Assume that the company begins year 1 with an initial inventory of 300,000 cans.
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.
An electronics firm is currently manufacturing anitem that has a variable cost of $.50 per unit and a selling priceof $1.00 per unit. Fixed costs are $14,000. Current volume is 30,000 units. The firm can substantially improve the productquality by adding a new piece of equipment at an additional fixedcost of $6,000. Variable cost would increase to $.60, but volumeshould jump to 50,000 units due to a higher-quality product.Should the company buy the new equipment?
Cluck Farms, Inc. produces a crop of chickens at a total cost of $66,000. The production generates 60,000 chickens that can be sold for $1.50 each to a slaughtering company, or the chickens can be slaughtered in house and then sold for $2.75 each. It costs $55,000 more to turn the annual chicken crop into chicken meat. If Chuck Farms slaughters the chickens, how much is the incremental profit or (loss)?
Jasmine is a mother of three children, ages 6 months, 2 years, and 3 and a half. Jasmine makes $24,000 a year at her full-time job, while her husband, Jamal, makes $45,000 a year. The daycare their children attend currently costs them $18,000 a year for all three children, but next year the cost is going up to $21,000. Jasmine wonders whether it’s even worth working, when she spends so much of her salary on childcare, and is considering quitting her job completely or working part-time instead. Jasmine’s dilemma is an example of a gendered process that occurs in the point of overlap of which two institutional arenas? the market and the family the family and the state the family and religion the state and the market
You have been asked to estimate the cost of 100 prefabricated structures to be sold to a local school district. Each structure provides 1,000 square feet offloor space, with 8-feet ceilings. In 1999, you produced 70 similar structures consistingof the same materials and having the same ceiling height, but each provided only 800square feet of floor space. The material cost for each structure was $25,000 in 1999, andthe cost capacity factor is 0.65. The cost index values for 1999 and 2006 are 200 and 289,respectively. The estimated manufacturing cost for the first 1,000-square-foot structureis $12,000. Assume a learning curve of 88% and use the cost of the 50th structure asyour standard time for estimating manufacturing cost. Estimate the total material costand the total manufacturing cost for the 100 prefabricated structures.

1. UST 40,000 (Commerce 5,000; Medicine 15%; AB 20%; Law 5% and others) Average price per computer device Php25,000 Average price per Apple device Php30,000 In UST, students from Commerce, Law, and AB purchased at least one (1) computer device in December 2020.
