Imagine you are working for a company that sells teleconferencing equipment. Draft a value proposition (list at least ten) for selling your equipment to a sales manager who has ten salespeople traveling two weeks a month to visit customers all over the country.

Sociologists and race theorists today make a confusing claim. "Race is not real, but it is real in the consequences of the belief in race. Race organizes the distribution of resources, power and life chances."

Alset Inc. hires you as a consultant, manufacturers of fine personalized drone. The market for

drones is growing quickly. The firm purchased some land three years ago for $1.44 million

expecting to use it as a toxic waste dump site. Few months ago Alset Inc. hired another firm to

dispose of all toxic materials. Based on a recent appraisal, the firm believes the current market

value of the land for $1.54 million on an after-tax basis. In four years, the land could be sold for

$1.64 million after taxes. The land will be utilized for the project.

The firm also hired a marketing firm to analyze the personalized drone market, at a cost of

$129,000. An excerpt of the marketing report is as follows:

The flying car industry will have a rapid expansion in the next four years. With the brand name

recognition that Alset brings to bear, we feel that the company will be able to sell 4,200, 5,100,

5,700, and 4,600 units each year for the next four years, respectively. Again, capitalizing on the

name recognition of Alset, we feel that a premium price of $690 can be charged for each

personalized drone. Because these drones appear to be a fad, we feel at the end of the four-year

period, sales should be discontinued.

Alset believes that fixed costs for the project will be $445,000 per year, and variable costs are 10

percent of sales. The equipment necessary for production will cost $3.9 million and will be

depreciated according to a three-year MACRS schedule. At the end of the project, the equipment

can be scrapped for $420,000. Net working capital of $129,000 will be required immediately.

Alset has a 40 percent tax rate, and the required return on the project is 14 percent.

2. Sally and Tom decide to go into business, which they call “Pelatone,” which manufactures and sells exercise bicycles. They sign a partnership agreement that requires Sally to contribute $100,000 and Tom to contribute $140,000 in capital to start the firm. The partnership agreement says nothing about the management of the firm or the division of profits. Without Sally’s knowledge, Tom informs the owner of United Wheel Co, that he represents the Pelatone and signs a large contract with United to buy wheels to be used on Pelatone’s bicycles. In its first year of operations, Pelatone makes a profit of $240,000.

1. What are the Tom’s and Sally’s rights with respect to the management of the firm?

2. Is Pelatone bound to the contract with United? Why or why not?

3. How should Pelatone’s first year’s profits be divided between Tom and Sally? Why?

Changing cash conversion cycle   Camp Manufacturing turns over its inventory 55 times each​ year, has an average payment period of 3636 days, and has an average collection period of 5959 days.

Your company produces electronic connectors, which consist of a metal strip with multiple prongs assembled into a plastic housing. The manufacturing process is divided into four separate departments: 1) Injection molding, where the small plastic housings are produced; 2) Stamping, where the steel strips are punched out of thin coils of steel; 3) Plating, where the steel strips, after being stamped, are plated with tin or gold; and 4) Assembly, where the plated strips are inserted into the plastic housing.

The injection molding machines together have the capacity to produce 4000 plastic housing per hour. The firm's stamping presses can punch out 3000 steel strips per hour. The plating department has two dedicated lines—one for tin-plating and the other for the slower gold-plating process. The tin-plating line has a capacity of 2000 units per hour; the gold-plating line has a capacity of 500 units per hour. In the assembly department, there are six automated assembly machines, each with the capacity to assemble 400 connectors per hour.

Assume that machines never break down, and assume that there is sufficient plastic and steel raw material so that raw material availability never constrains the process. Assume that the plant is only running the tin-plated product—the gold-plating line is completely idle.

1) Assume that hourly demand during work hours for tin-plated connectors is 2200 units/hr and demand for gold-plated connectors is 600 units/hr, and that both processes are active. The plant runs for 8 hours/day, 5 days/week, 50 weeks/yr. Both connector types earn a margin of $0.10 apiece. The plant is considering investing in an additional automated assembly machine, which costs $400,000. What is the payback period for this investment (in years)?

BC Co.’s assets consist of $20 thousands in cash and three investment projects. The firm hasno debt outstanding. The company can borrow and lend at 12% per year. Each project lasts foronly one year. The table below lists the cash flows from the projects at the initial date (t= 0)and at the end of the year (t= 1). Cash outflows are listed as negative numbers, while cashinflows are listed as positive. All figures are in thousands of dollars.

You are studying a population of wild turtles on a remote Pacific island. You have been following the allelic frequencies at a single two-allele locus 'S', which controls embryonic survival through simple Mendelian inheritance with dominance. The population has been in Hardy-Weinberg equilibrium at this locus for many generations.

At Hardy-Weinberg equilibrium, the frequency of the recessive allele S^d is 0.88

The genotypic frequencies at Hardy-Weinberg equilibrium are as follows:

f(S^DS^D) = 0.0144

f(S^DS^d) = 0.2112

f(S^dS^d) = 0.7744

An increase in ocean temperature between 2018 and 2019 is thought to have driven the population away from Hardy-Weinberg equilibrium at the S locus.

The numbers of sampled offspring by genotype after the 2019 hatch are as follows:

S^DS^D : 200

S^DS^d : 200

S^dS^d : 40

Calculate the relative fitness (W) values for each genotype (you will need all these values in a subsequent step).

a) The relative fitness value for the S^dS^d genotype is [A] (enter your answer as a decimal in the form '0.x'; do not spell out the number as a word; there are no units to include)

b) The type or form of natural selection that has occurred is [B] (use the specific phrase that describes this form of selection completely!).

Now, calculate all genotypic frequencies in the 2019 offspring (first generation after selection):

c) post-selection f(S^DS^D) = [C] (perform this and the following two calculations (d and e) to four significant figures after the decimal point; enter your answers in the exact form '0.wxyz'; make sure to round off correctly; there are no units)

d) post-selection f(S^DS^d) = [D]

e) post-selection f(S^dS^d) = [E]

f) The frequency of the S^d recessive allele in the 2019 offspring (first generation after selection) is [F] (perform the calculation with four significant figures, then round off to 2 significant figures in the final answer; enter your answer in the exact form '0.xy')

One expert contends that sales training is not at all complicated. He predicts that regardless of advances in communication, resources, technology, and training tools, the basic selling skills that trainers teach salespeople will change very little from those that have been successful during the past 50 years. What will change, according to the expert, is how salespeople are trained to use these skills effectively. Do you agree with this prediction?
