Answer: d. stock prices of U.S. nuclear plants increased.
Explanation:
Chernobyl was a nuclear power plant in the former Soviet Union that was being used to produce electricity until it suffered a meltdown that effectively rendered the surrounding areas unlivable.
In response to this disaster, the stock prices of U.S. nuclear power plants went up because the Soviet meltdown not only reduced the supply of nuclear powered electricity but also showed that American engineering was superior and so people bought more American nuclear plant shares which took its price up.

Suppose that a Country Club is considering what price to charge for adults. They know that if they charge a price of $100 then 70 adults will join and if they charge a price of $120 then 50 adults will join. What is the absolute value of the price elasticity of demand for adults at this Country Club
Answer:
1.43
Explanation:
Price elasticity of demand measures the responsiveness of quantity demanded to changes in price of the good.
Price elasticity of demand = percentage change in quantity demanded / percentage change in price
Price =120 /100 - 1 = 0.2
Quantity = 50/ 70 - 1 = 0.2857
0.2857 / 0.2 = 1.43
If the absolute value of price elasticity is greater than one, it means demand is elastic. Elastic demand means that quantity demanded is sensitive to price changes.
Demand is inelastic if a small change in price has little or no effect on quantity demanded. The absolute value of elasticity would be less than one
Demand is unit elastic if a small change in price has an equal and proportionate effect on quantity demanded.
Infinitely elastic demand is perfectly elastic demand. Demand falls to zero when price increases
Perfectly inelastic demand is demand where there is no change in the quantity demanded regardless of changes in price
p = 0,2
=0.2857
Question 3 4 Marks Mi Tierra Driving School charges $680 per student to prepare and administer written and driving tests. Variable costs of $408 per student include trainers’ wages, study materials, and gasoline. Annual fixed costs of $63,920 include the training facility and fleet of cars. Requirements 1. For each of the following independent situations, calculate the contribution margin per unit and the breakeven point in units by first referring to the original data provided: a. Breakeven point with no change in information. b. Decrease sales price to $544 per student. c. Decrease variable costs to $340 per student. d. Decrease fixed costs to $53,040.
Answer:
Results are below.
Explanation:
Giving the following information:
Selling price= $680
Unitary variable cost= $408
Fixed cost= $63,920
To calculate the contribution margin and break-even point in units, we need to use the following formula:
Unitary contribution margin= selling price - unitary variable cost
Break-even point in units= fixed costs/ contribution margin per unit
a:
Unitary contribution margin= 680 - 408= $272
Break-even point in units= 63,920 / 272
Break-even point in units= 235
b:
Unitary contribution margin= 544 - 408= $136
Break-even point in units= 63,920 / 136
Break-even point in units= 470
c:
Unitary contribution margin= 680 - 340= $340
Break-even point in units= 63,920 / 340
Break-even point in units= 188
d:
Unitary contribution margin= 680 - 408= $272
Break-even point in units= 53,040 / 272
Break-even point in units= 195
Lucy has been the sole shareholder of a calendar year S corporation since 1980. At the end of 2011, Lucy's stock basis is $23,500, and she receives a distribution of $25,000. Corporate level accounts are computed as follows.
AAA 7,000
PTI 11,000
Accumulated E&P 600
How much capital gain, if any, will Lucy have?
a. $600
b. $7,000
c. $6,400
d. $900
e. None of the above
Answer: d. $900
Explanation:
Capital gain = Total distribution - AAA as this isn't taxed - Accumulated E&P - PTI which isn't taxed either - Stock basis
Stock basis = Stock basis - AAA - PTI
= 23,500 - 7,000 - 11,000
= $5,500
Capital Gain = 25,000 - 7,000 - 600 - 11,000 - 5,500
= $900

If there is a shortage in the market, the market price is too _______________. The quantity demanded will be ________________ the quantity supplied. Thus, the market price must ____________ , which will _____________ the quantity supplied and ____________ the quantity demanded.
Answer:
low
greater
increase
increase
decrease
Explanation:
Equilibrium price is the price at which quantity demand equal quantity supplied. Above equilibrium price there is a surplus - quantity supplied exceeds quantity demanded.
Below equilibrium price there is a shortage - quantity demanded exceeds quantity supplied
When there is a shortage in the market, the market price is too low. As a result, quantity demanded exceeds quantity supplied. Shortage would lead to an increase in price towards equilibrium. This would lead to an increase in the quantity supplied and a decrease in quantity demanded

Texas Curtain Works is in the process of preparing its budget for next year. Cost of goods sold has been estimated at 70 percent of sales. Fabric purchases and payments are to be made during the month preceding the month of sale. Wages are estimated at 20 percent of sales and are paid during the month of sale. Other operating costs amounting to 25 percent of sales are to be paid in the month following the month of sales. Sales revenue is forecasted as follows:
Month Sales
February $440,000
March $450,000
April $480,000
May $500,000
June $510,000
What is the amount of fabric purchases during the month of March?
a) $480,000
b) $336,000
c) $288,000
d) $300,000
Answer:
b. $336,000
Explanation:
Here, the Fabric purchases & payments are to be made during the month before the month of sale.
The Amount of fabric purchases during the month of march = 70% of sales of the month of April
Purchases of March = 70% * $480,000
Purchases of March = 0.70 *$480,000
Purchases of March = $336,000
So, the amount of fabric purchases during the month of March is $336,000.
The CEO of Kwikee Shoppe, a chain of convenience stores, believes that some of his managers aren’t making decisions as effectively as they could. He has hired you as a consultant to analyze the types of bias that could be causing poor decisions. If you can identify the biases that may cloud their judgment, then they can be made aware of these tendencies so they can improve their performance. You gather data about Kwikee Shoppe managers’ most recent decisions.
Stella is in charge of the western region, and she has a strong track record of opening new stores that perform well and closing stores that could not contribute satisfactorily to the bottom line. Lately, however, many of her new stores have had below average performance, and she has closed some stores that probably could have been turned around by putting a different store manager in charge, advertising more, or offering more specials on popular products. Nonetheless, Stella knows that she is great at her job. Which of the following would not be a way for Stella overcome this bias?
A. Consult with other regional managers for their opinion before closing stores.
B. Before closing a store, replace the manager with one from a successful store and revisit the decision in 90 days.
C. Create a checklist of items to ask before closing stores, providing weights to each item based on their importance.
D. Focus on the stores that she closed that would not have improved with a different manager in place, additional advertising, or sales.
Answer:
Kwikee Shoppe
The way that Stella would overcome this bias is:
D. Focus on the stores that she closed that would not have improved with a different manager in place, additional advertising, or sales.
Explanation:
The other listed actions would enable Stella to overcome her personal bias, which may be clouding her sense of judgment. The focus on the stores that she had closed would only puff her ego instead of reducing bias. To focus on the past when Stella is proud of her achievements cannot allow her to objectively review the situation in order to improve on her decisions and performance.
Assume that as their leader, you wanted to influence minimum wage earners in a plastic bottle recycling center to work faster. Which one or two influence tactics are likely to be effective
Answer:
An effective leader is one who is able to influence his team through his communication and interpersonal skills.
In order to achieve greater speed and productivity at work, some influencing tactics that can be effective in a recycling center where workers earn a minimum wage may be associated with the leader's ability to empathize with the team, recognizing the difficulties and challenges of the work, but acting in a comprehensive, ethical way and helping them in their demands, exercising practical leadership, where the leader is the first to set a positive example of what he wants to achieve.
In this market, the equilibrium hourly wage is $ , and the equilibrium quantity of labor is thousand workers. Suppose a senator introduces a bill to legislate a minimum hourly wage of $6. This type of price control is called a .
Answer:
The equilibrium hourly wage is the wage where the curve of supply of labor intersects with that of the demand for labor. The same goes for the equilibrium quantity of labor.
The equilibrium hourly wage is $10, and the equilibrium quantity of labor is 450 thousand workers.
If a Senator introduces a minimum hourly wage, this is considered a Price Floor.
Price floors are prices that that the government mandates that one cannot charge below for a good or service. If there is a price floor on cake for instance, a person is not allowed to charge less than that price floor for cake. The Senator's bill is therefore saying that people should not be paid less than $6 an hour.
An example of fast tracking a project schedule would be to overlap the design and production phases for a design-to-production project, where the conventional approach would be to move on to construction only after completing the design phase.
a. True
b. False
Answer:
a. True
Explanation:
Project management can be defined as the process of designing, planning, developing, leading and execution of a project plan or activities using a set of skills, tools, knowledge, techniques and experience to achieve the set goals and objectives of creating a unique product or service.
Generally, projects are considered to be temporary because they usually have a start-time and an end-time to complete, execute or implement the project plan.
Furthermore, the main purpose of project management is working toward a common goal.
This ultimately implies that, project managers should ensure adequate attention and time is taken to identify, analyze and manage capital, raw materials, people, system of tasks and other resources, so as to effectively and efficiently achieve a common goal with all project stakeholders.
The fundamentals of Project Management includes;
1. Project initiation
2. Project planning
3. Project execution
4. Monitoring and controlling of the project.
5. Adapting and closure of project.
In the execution of a project, delaying a task normally affects the start or finishing time of the other tasks (successors) in a project.
The amount of time that is permitted for an activity to be delayed without delaying the early start date of any immediately following (succeeding) activities refers to the free slack or having an adverse effect on entire project.
A project schedule can be defined as a plan that comprises of the deliverables, activities and milestones with respect to a project, especially by including the intended start and finish dates.
The time for the implementation or execution of a project can be fast-tracked by a project manager.
For example, you can fast-track a design-to-production project by overlapping the design and production phases; especially by moving on to construction only after completing the design phase.

Find the intrinsic value of XYZ Inc. The DPS at the end of year 1 is $2.00; at the end of year 2 is $2.40; at the end of year 3 is $2.70. After the third year, the DPS grows at a constant rate of 5%. The required rate of return is 12%.
Answer: 34.33
Explanation:
Firstly, we'll calculate the terminal value
which willl be:
= 2.70 × (1+5%)/(12% - 5%)
= 2.70 x 1.05/(0.12 - 0.05)
= 40.5
Then, the intrinsic value will be:
= 2/1.12 + 2.4/1.12² + (2.7 + 40.5)/1.12³
= 34.33
Therefore, the the intrinsic value of XYZ Inc is 34.33

Thirsty Cactus Corp. just paid a dividend of $1.50 per share. The dividends are expected to grow at 25 percent for the next 9 years and then level off to a 5 percent growth rate indefinitely. If the required return is 13 percent, what is the price of the stock today?
Answer:
$143.40
Explanation:
The dividend for the next year = [tex]\text{ current year dividend} \times (1 + \text{growth})[/tex]
= $ 1.50 x (1 + 0.13)
= 1.50 x 1.30
= $ 1.95
The dividend in the second year = 1.95 x 1.30
= $ 2.54
Similarly, the dividend for the year 9 is = [tex]$1.50 \times (1.30)^9$[/tex]
= $ 15.91
The value of the stock at the end of year 9,
[tex]$=\frac{\text{Dividend of year 10}}{\text{(Required rate of return - Growth rate)}}$[/tex]
[tex]$=\frac{15.91\times1.05}{0.13-0.05}$[/tex]
= $ 208.81
The present value factor [tex]$=\frac{1}{(1+r)^n}$[/tex]
where, r = rate of interest = 13% = 0.13
n = years (1 to 9)
So, the present value factor for the 2nd year is [tex]$=\frac{1}{(1+0.13)^2}$[/tex]
[tex]$=\frac{1}{(1.13)^2}$[/tex]
[tex]$=\frac{1}{1.2769}$[/tex]
= 0.783147
Therefore, the price of the stock today is calculated as to be $ 143.40

1/2 for most recent , 1/3 for second most recent and 1/6 for third most recent observation
Given data :
Week Sales (1000s of gallons)
1 16
2 20
3 20
4 23
5 18
6 17
7 19
8 23
9 19
10 14
11 21
solution attached below
B) Determine MSE for the weighted moving average
MSE = ∑ (error)^2 / 8
= 116.0289 / 8 = 14.50
The MSE for unweighted moving average ( 8.90 ) is smaller than the MSE for weighted moving average
C) Yes I will find a weight that makes at least the MSE for weighted moving average than unweighted moving average
