An office has 5 copy machines that need to be serviced approximately once an hour either for paper, staples, or toner or repair. Each machine therefore runs approximately 1 hour before needing some attention. The average service time is 7 minutes. Copier downtime in this busy office costs approximately $20 per hour. The cost of attendant is $15 per hour. Using the finite queuing analysis, answer the following questions:________.
a. What is the average number of copiers in line?
b. What is the average number of copiers still in operation?
c. What is the average number of copiers being serviced?
d. The firm is considering adding another attendant at the same $15 rate. Should the office do it?
Answers
Answer:
a. Average number of copiers in line is 0.275
b. Average number of copiers still in operation is 4.23
c. Average number being serviced is 0.496
d. No, the office should not do it
Explanation:
N = number of copy machines = 5
U = average time between unit service requirements = 1 hour = 60 minutes
T = average service time = 7 minutes
M = number of servers = 1
Cost of copier downtime = $20
Cost of attendant = $15
(a) Service factor, X = T / (T+U) = 7 / (60+7) = 0.105
From the Finite Queuing Tables for a Population of N = 5,
For X = 0.105 and M=1, the efficiency factor, F = 0.945
So, The average number waiting in line, L = N × (1 - F) = 5 × (1 - 0.945) = 0.275
(b) Average number in operation, J = N×F×(1 - X) = 5×0.945×(1 - 0.105) = 4.23
(c) Average number being serviced, H = F×N×X = 0.945×5×0.105 = 0.496
(d) For M=1
The average number of copier down = N - J = 5 - 4.23 = 0.77
So, cost of downtime per hour = $20×0.77 = $15.4
Also, the cost of the server per hour = $15×M = $15×1 = $15
So, total cost = 15.4 + 15 = $30.4 per hour (i)
For M=2
From the Finite Queuing Tables for a Population of N = 5, with X = 0.105 and M=2, the efficiency factor, F = 0.997
J = N×F×(1 - X) = 5×0.997×(1 - 0.105) = 4.46
The average number of copier down = N - J = 5 - 4.46 = 0.54
So, cost of downtime per hour = $20×0.54 = $10.8
Also, the cost of the server per hour = $15×M = $15×2 = $30
So, total cost = 10.8 + 30 = $40.8 per hour (ii)
Comparing (i) and (ii), we can say that having another attendant is not cost-effective.

Utilities firms are one example of a monopoly among the possibilities given. When they are the exclusive provider of these necessary services in a certain region, utility firms, such as those that provide electricity, water, or natural gas, frequently act as Monopoly. As a result, customers are virtually forced to adopt the services offered by the local utility company since they have no other alternatives.
The Landlord's Game, which was developed by Lizzie Magie in the United States in 1903 to advance Henry George's economic theories, particularly his views on taxation, and to show that an economy that rewards Utilities individuals is preferable to one in which monopolies hold all the wealth, is the source of Monopoly.

Answers
Shares refer to a unit of ownership in a company, also known as stocks. The shares are purchased by investors, and the amount of shares an investor buys is proportional to the percentage of ownership in the company. There are two primary types of shares, which are Ordinary shares and Preference shares.
Ordinary shares Ordinary shares are the most common types of shares that companies offer. Owners of these shares have voting rights at the company's general meetings, and they get a proportion of the company's profits in the form of dividends. The shareholders are typically last in line in the event of bankruptcy, and they receive the least priority in payment.
Preference shares Preference shares are those shares that offer preference over the ordinary shares in terms of dividend payments. The preference shareholders receive dividends before the ordinary shareholders. Preference shares have two categories: cumulative preference shares and non-cumulative preference shares. Cumulative preference shareholders receive their unpaid dividends before the ordinary shareholders, and non-cumulative preference shareholders don't receive their unpaid dividends if the company isn't making any profits. Preference shareholders don't have voting rights in most cases, but they do get the advantage of receiving dividends before the ordinary shareholders.
In conclusion, understanding the different types of shares is vital for investors to make informed investment decisions. By knowing what each type of share entails, investors can choose the right type of share that suits their investment goals.

A positive correlation is a relationship between two variables that run in parallel. In the same direction. A positive correlation occurs when one variable decreases when the other variable decreases, or when one variable increases while the other variable increases. Since these two different variables are moving in the same direction, they are theoretically subject to the same external force.

B. Spending your full credit limit before making a payment
O
C. Ensuring that all of your credit card bills are paid on time
D. Paying only the minimum monthly payment on all credit cards
SUBMIT
Answers
Answer: C. Ensuring that all of your credit card bills are paid on time
Explanation:
Paying your credit card balance in time will mean that you won't get charged interest or any other fees. This assumes there's no annual fee or any other kind of fee. It's possible with some cards that you can use them without any interest attached at all. Simply pay off the balance.
The credit card company banks on the fact that many people either can't or forget to pay off the month's balance, which incurs penalties and other fees. The credit card company also hopes that people pay the minimum monthly payment, which is the slowest way to pay off the debt and incurs the highest amount of fees. This option is definitely not recommended. So we can rule out choice D.
We can also rule out choices A and B. The goal is to have the lowest interest rate as possible. The lower the rate, the lower the interest if any applies. Choice B is a bad idea because you should have some cushion in your credit card balance.

Answers
The penalty charge is $728.04.
To find the penalty charge in the given scenario where Molly Ellen forgot to send the payroll taxes due on April 15th and sent the payment on November 8th, we will follow these steps:Calculate the days from April 15 to November 8 which is 207 daysCompute the exact interest on the unpaid taxes using the exact interest formula: I=P*R*T/100I: Exact interestP: Unpaid taxes ($4,000)R: Rate (9.20%)T: Time in years (207 days/365 days = 0.57 years)
Calculate the penalty by subtracting the unpaid taxes from the total amount due including the interestPenalty = Total amount due - Unpaid taxesGiven that the unpaid taxes were $4,000, and the IRS sent a penalty charge of 9.20% simple interest on the unpaid taxes. Using the above information, we will calculate the penalty as follows:
Days from April 15th to November 8th is 207 days.The exact interest formula is I=P*R*T/100, where I is the exact interest, P is the principal, R is the rate and T is the time in years.I = (4000 * 9.20 * 207)/100 * 365 = $728.04The total amount due including the interest is $4,728.04.Penalty = Total amount due - Unpaid taxesPenalty = $4728.04 - $4000Penalty = $728.04Therefore, the penalty charge is $728.04.

You charge $500 on each of your two credit cards.
One is American Express with an interest rate of 15.99%.
The other is Chase Sapphire with an interest rate of
20.99%. Assuming that you are only making the minimum
payment of $25 to each of the credit card companies,
which card will you pay off first
Answers
It is advisable to pay off the Chase Sapphire card first to minimize the overall interest paid.
To determine which credit card to pay off first, we need to consider the interest rates and the minimum payment amounts. Let's calculate the interest accrued on each card and compare the total amounts.
For the American Express card with a balance of $500 and an interest rate of 15.99%, the interest accrued per month would be (15.99/100) * (500) = $79.95. With a minimum payment of $25, the remaining balance after the payment would be $500 - $25 = $475.
For the Chase Sapphire card with a balance of $500 and an interest rate of 20.99%, the interest accrued per month would be (20.99/100) * (500) = $104.95. After making the minimum payment of $25, the remaining balance would be $500 - $25 = $475.
Comparing the two cards, we see that the interest accrued on the Chase Sapphire card is higher ($104.95) compared to the American Express card ($79.95). Therefore, it is advisable to pay off the Chase Sapphire card first to minimize the overall interest paid.
