Answer:
the geometric returns of Stock ABC for six years is 5.02%
Explanation:
The computation of the geometric returns of Stock ABC for six years is given below:
= [(1 + r1) × (1 + r2) × (1 + r3) × (1 + r4) × (1 + r5) × (1 + r6)]^1 ÷ 6 - 1
= [(1 + 0.10) × (1 - 0.15) × (1 + 0.20) × (1 + 0.22) × (1 - 0.30) × (1 + 0.40)]^(1 ÷ 6) - 1
= 0.0502 or 5.02%
Hence, the geometric returns of Stock ABC for six years is 5.02%
The above formula should be applied

Emma's use of good x does not affect anyone else's use of good x. Neither Emma nor anyone else can be prevented from using the good. Good x is an example of the type of good that belongs in:________
a. Box D, which represents public goods.
b. Box B, which represents common resources.
c. Box C, which represents common resources.
d. Box A, which represents private goods.
Answer: A. Box D, which represents public goods.
Explanation:
A public good is referred to as a good that possesses two main characteristics which are non-rivalrous and non-excludable.
This simply means that individuals nobody can be excluded from using a public good and.itsuse by one individual doesn't affect others from using it too.
Since Emma's use of good x does not affect anyone else's use of good x and neither Emma nor anyone else can be prevented from using the good, then it's a public good.
Wilturner Company incurs $80,000 of labor related directly to the product in the Assembly Department, and $29,000 of labor related to the Assembly Department as a whole, and $16,000 of labor for services that help production in both the Assembly and Finishing departments. The amount of direct labor and factory overhead respectively are:________
Answer:
Direct labor = $80,000Factory Overhead = $29,000Explanation:
Direct labor is the cost of labor that was involved in the actual production process.
Factory overhead is the labor that was involved in the production but not directly involved.
Direct labor here is therefore the $80,000 that was directly related to the product.
Factory overhead is the $29,000 that was related to the Assembly department as a whole.

how does mcdonaldization affect global relationships?
Answer:
The term McDonalization refers to a sociological and cultural concept by which the situation of depersonalization and automation of social relations and the means of economic production is described, by which it aims to generate automated structures such as those of fast food chains with the objective of optimizing performance and generating efficiency, at the expense of depersonalizing labor and social relations, leading individuals to a greater loss of their collective sentiment.
Walbin Corporation uses the weighted-average method in its process costing system. The beginning work in process inventory in a particular department consisted of 15,500 units, 100% complete with respect to materials cost and 20% complete with respect to conversion costs. The total cost in the beginning work in process inventory was $25,200. A total of 53,000 units were transferred out of the department during the month. The costs per equivalent unit were computed to be $1.6 for materials and $3.3 for conversion costs. The total cost of the units completed and transferred out of the department was:
a. $259,700
b. $254,180
c. $189,740
d. $225,380
Answer:
a. $259,700
Explanation:
The computation of the total cost of the units completed and transferred out of the department is given below:
= 53,000 units × $1.6 + 53,000 un$its × $3.3
= $84,800 + $174,900
= $259,700
Hence, the total cost of the units completed and transferred out of the department is $259,700
A sporting goods manufacturer budgets production of 45,000 pairs of ski boots in the first quarter and 30,000 pairs in the second quarter of the upcoming year. Each pair of boots require 2 kg of a key raw material. The company aims to end each quarter with ending raw materials inventory equal to 20% of the following quarter's material needs. Beginning inventory for this material is 18,000 kg and the cost per kg is $8. What is the budgeted materials need in kg. in the first quarter?
A) 90,000 kg.
B) 84,000 kg.
C) 108,000 kg.
D) 102,000 kg.
E) 120,000 kg.
Answer:
B) 84,000 kg.
Explanation:
The computation of the budgeted materials need in kg. in the first quarter is given below:
begnning inventory 18000
required for production (45000 × 2) 90000
Less: closing (30000 × 2 × 20%) - 12000
Raw material needs 84000
hence, the budgeted materials need in kg. in the first quarter is 84,000
Therefore the option b is correct
Closing entries are: Multiple Choice Made to record events that occurred during the period but have not yet been recorded. Made to transfer the balances of temporary accounts to retained earnings. Made to transfer the balances of permanent accounts to retained earnings. Optional.
Answer:
Made to transfer the balances of temporary accounts to retained earnings.
Explanation:
Financial statements can be defined as a document used for the formal communication or disclosure of financial information and statements to present and potential users such as investors and creditors.
Generally, financial statements are the formally written records of the business and financial activities of a business entity or organization.
There are four (4) main types of financial statements and these are;
1. Balance sheet: it contains financial information about assets, liability, and equity.
2. Cash flow statement: it contains financial information about operating, financial and investing activities.
3. Income statement: it contains financial information about the income and expenses of an organization.
4. Statement of changes in equity: it contains financial information about profits or loss, dividends, etc.
A closing entry can be defined as a journal entry made at the end of an accounting period to transfer all balances in the temporary accounts to a permanent account.
In Financial accounting, there are four (4) main closing entries and these include;
I. Closing expenses to income summary.
II. Closing revenues to income summary.
III. Closing dividends to retained earnings.
IV. Closing income summary to retained earnings.
This ultimately implies that, closing entries are made to transfer the balances of temporary accounts to retained earnings.
Retained earnings also known as accumulated earnings, can be defined as the total amount of net income held by a corporation for its future use after paying out dividends to its shareholders.
The retained earnings statement refers to a financial statement that enumerate changes in retained earnings for an organization over a specific period of time. The retained earnings statement is the statement of owner's equity that outlines details of changes in the amount of retained earnings (profits) over a specified period in an organization.

what are the good characteristics of an entrepreneur?
Answer:
Enterprises are usually regarded as the start-up of a company. Although this is true, some nuances need to be taken into account.
Entrepreneurs — either as individuals or as a team — find their own personal and professional opportunities. They make hypotheses of ways in which they can give customers value and conduct structured testing to validate their ideas.
Explanation:
Curiosity:-
Successful entrepreneurs feel curious and can constantly search for new opportunities. Curious entrepreneurs ask questions and explore different avenues rather than settling for what they think they know.
Structured Experimentation:-
The Need for structured experimentation is in conjunction with curiosity. An entrepreneur must conduct tests to determine if each new opportunity arises.
Adaptability:-
The company is changing constantly. Entrepreneurship is an iterative process that presents itself at all times with new challenges and opportunities. For every scenario, it is almost impossible to prepare.
Team Building:-
A big businessman knows their weaknesses and strengths. They build well-rounded teams that complement their ability instead of letting weaknesses hold them back.
Risk Tolerance:-
Business is often linked to risk. Although it is true that starting a business requires a contractor to take risks, they also need to do something to minimize it.
Comfortable with Failure:-
Successful entrepreneurs prepare and comfortably confront failure. The possibility of success pushes them forward rather than allow fear to hold them back.
Persistence:-
Although many successful businessmen can comfortably fail, this does not mean that they can abandon quickly. Rather, they regard failures as learning and growing opportunities.
Two identical firms compete as a Cournot duopoly. The inverse market demand they face is P = 128 - 4Q. The total cost function for each firm is TC(Q) = 8Q. The price charged in this market will be
Answer: 48
Explanation:
Since TC(Q) = 8Q, the marginal cost(MC) will be = dC/dQ = 8
P = 128 - 4Q.
P = 128 - 4Q1 - 4Q2
For firm 1, the Total revenue will be:
= 128Q1 - 4Q1²- 4Q1Q2
MR1 = 128 - 8Q1 - 4Q2
Then, we'll set MR1 = MC1,
128 - 8Q1 - 4Q2 = 8
Collect like terms
8Q1 + 4Q2 = 120 .........(1)
For firm 2,
TR2 = 128Q2 - 4Q1Q2 - 4Q2²
MR2 = 128 - 4Q1 - 8Q2
Then we'll set MR2 = MC2,
128 - 4Q1 - 8Q2 = 8
4Q1 + 8Q2 = 120..........(2)
Thenz we'll multiply equation (2) by 2 and this will be:
8Q1 + 16Q2 = 240 ........(3)
8Q1 + 4Q2 = 120.........(1)
Equation (3) - equation (1) will give:
12Q2 = 120
Q2 = 120/12
Q2 = 10
Since the cost function for both firms is identical, then Q1 = 10 as well.
Q = Q1 + Q2
Q = 10 + 10
Q = 20
P = 128 - 4Q
P = 128 - (4 x 20)
P = 128 - 80
P = 48
The price charged in the market is 48.
Suver Corporation has a standard costing system. The following data are available for June: Actual quantity of direct materials purchased 20,000 pounds Standard price of direct materials $ 3.00 per pound Material price variance $ 2,000 Unfavorable Material quantity variance $ 4,000 Favorable The actual price per pound of direct materials purchased in June was:
Answer: $3.10
Explanation:
The actual price per pound of direct materials purchased in June will be calculated as follows:
Let the actual price be represented by x.
Material price variance is calculated as:
= (standard price-actual price) × actual quantity
-2000 = (3 × 20000) - 20000x
-2000 = 60000 - 20000x
20000x = 60000 + 2000
20000x = 62000
x = 62000/20000
x = 3.1
Therefore, the actual price per pound of direct material bought in June is $3.10
XYZ Manufacturing produces a single product that sells for $105. Variable costs per unit equal $74. The company expects total fixed costs to be $97,000 for the next month at the projected sales level of 3,200 units. To improve performance, management is considering several alternative actions. Each situation is to be evaluated separately. Suppose that management believes that a 10% reduction in the selling price will result in a 10% increase in sales. If this proposed reduction in selling price is implemented:__________
a. operating income will decrease by $8,000.
b. operating income will increase by $8,000.
c. operating income will decrease by $16,000.
d. operating income will increase by $16,000.
Answer:
Effect on income= $6,880 increase
Explanation:
First, we need to calculate the new selling price and the increase in the number of units sold:
Selling price= 105 / (1.1)= $95.5
Increase in number of units sold= 3,200*0.1= 320
Now, the effect on the income of the changes:
Effect on income= increase in total contribution margin
Effect on income= 320*(95.5 - 74)
Effect on income= $6,880 increase
n Office Manager uses a Periodic Review Inventory System: they check the inventory in their Office Supply Closet once every 10 days, placing an order with their supplier depending on the inventory level of the office supplies. The manager has set a restocking level of 300 post it notes for their closet. This week, the manager has counted 140 post it notes in the closet. How many post it notes will the manager order from their supplier? In other words, what is the Order Quantity?
Answer: 160
Explanation:
The number of post it notes that the manager will order from their supplier will be the difference between the restocking level and the inventory at the time of review. This will be:
= Restocking level - Inventory at the time of review
= 300 - 140
= 160
Therefore, the order quantity is 160.
You are going to retire in 43 years. After retirement, you need $80,000 at the end of year for 25 years. How much do you have to save for your retirement every month
Answer:
Results are below.
Explanation:
I will assume an interest rate of 8% per year.
First, we need to calculate the amount required at the moment of retirement:
PV= A*{(1/i) - 1/[i*(1 + i)^n]}
PV= 80,000 * {(1/0.08) - 1/[0.08*(1.08^25)]}
PV= $853,982.1
Now, the monthly deposit required:
i= 0.08/12= 0.0067
n= 43*12= 516
FV= {A*[(1+i)^n-1]}/i
A= monthly deposit
Isolating A:
A= (FV*i)/{[(1+i)^n]-1}
A= (853,982.1*0.0067) / [(1.0067^516) - 1]
A= $188.43
An operating lease has unequal payments over the lease term. During the first year, the payment is $14,000; total payments over the five-year lease term are $120,000. Based on the present value of the total lease payments and the implicit interest rate, interest expense incurred during the first year is $6,000. Amortization of the right-to-use asset for year 1 should be:
Answer: $8000
Explanation:
Amortization refers to the practice whereby the cost of an intangible asset is spread over the useful life of the asset. Amortization is used to lower the book value of an intangible asset or loan over a particular period of time.
Based on the information given in the question, the amortization of the right-to-use asset for year 1 should be:
= Installment - Interest
= $14000 - $6000
= $8000

Your company is estimated to make dividends payments of $2.2 next year, $3.9 the year after, and $4.8 in the year after that. The dividends will then grow at a constant rate of 2% per year. If the discount rate is 9% then what is the current stock price?
Answer:
$63.01
Explanation:
The share price today is the present value of expected future cash flows which in this case are the expected future dividends and the terminal value of dividends beyond the 3rd year.
Year 1 dividend =$2.2
Year 2 dividend =$3.9
Year 3 dividend =$4.8
Terminal value=Year 3 dividend*(1+constant growth rate)/(required rate of return-constant growth rate)
constant growth rate=2%
the required rate of return=9%
Terminal value=$4.80*(1+2%)/(9%-2%)
Terminal value=$69.94
Present value of a future cash flow=cash flow/(1+required rate of return)^n
n is 1 for year 1 dividend, 2 for year 2 dividend , 3 for year 3 dividend, and terminal value(terminal value is stated in year 3 terms)
stock price=$2.2/(1+9%)^1+$3.9/(1+9%)^2+$4.8/(1+9%)^3+$69.94/(1+9%)^3
stock price=$63.01
Gantner Company had the following department information about physical units and percentage of completion: Ch21_Q64 If materials are added at the beginning of the production process, what is the total number of equivalent units for materials during May
Answer:
200,000 units
Explanation:
The computation of the total no of equivalent units for material during may month is given below:
Units added during May is
= 150,000 + 50,000
= 200,000 units.
Hence, the total no of equivalent units for material during may month is 200,000 units
The same should be considered and relevant
Baker Company produced 1,500 units in May at a total cost of $10,000 and 4,000 units in June at a total cost of $18,000. Compute the variable cost per unit and the total fixed cost using the high-low method.
Answer:
Variable cost per unit = 3.2
TFC = 5200
Explanation:
Below is the given values:
Unit of may = 1500 units
Total cost of may = $10000
Unit of June = 4000
Total cost of June = $18000
Use below formula to find the variable cost per unit:
Variable cost per unit = (Tota cost of high activity - Total cost of low activity) / (High activity unit - lowest activity unit)
Variable cost per unit = (18000 - 10000) / (4000 - 1500)
Variable cost per unit = 3.2
Total Cost=(VC×Units Produced)+Total Fixed Cost
18000 = (3.2 x 4000) + TFC
Total fixed cost = 18000 - (3.2 x 4000)
Total fixed cost = $5200

The customer service department for a wholesale electronics outlet claims 90% of all customer complaints are resolved to the satisfaction of the customer. In order to test this claim, a random sample of 15 customers who have filed complaints is selected. Part A
Let x = the number of sampled customers whose complaints were solved to the customer’s satisfaction. Assuming the claim is true, write the binomial formula for the situation. Part B Use the binomial tables (see Table A.1in the text) to find each of the following if we assume that the claim is tru:
Answer:
Kindly check explanation
Explanation:
Given
Probability of success, p = 0.9
Number of trials = sample size, n = 15
q = 1 - p
The binomial formula for this situation is written as :
P(x = x) = nCx * p^x * q^(n-x)
P(x = x) = 15Cx * 0.9^x * (1-0.9)^(15-x)
(1) For ; P(x ≤ 13).
P(x = 0) + p(x = 1) +... + p(x = 13)
Using a calculator :
P(x ≤ 13) = 0.451 (3 decimal place)
(2) For ; P(x > 10).
Using calculator :
P(x > 10) = p(x = 11) + p(x = 12) +... + p(x = 15)
P(x > 10) = 0.9873
(3) For P(x ≥ 14).
Using calculator ;
P(x ≥ 14) = [p(x = 14) + p(x = 15)]
P(x ≥ 14) = 0.5490
(4) P(9 ≤ x ≤ 12).
P(9 ≤ x ≤ 12) = p(x = 9) + p(x = 10) + p(x = 11) + p(x = 12)
P(9 ≤ x ≤ 12) = (0.001939 + 0.01047 + 0.042835 + 0.128505) = 0.1837
(5) For P(x ≤ 9) ;
Using calculator ;
P(x ≤ 9) = p(x = 0) + p(x = 1) +... + p(x = 9)
P(x ≤ 9) = 0.00225
