Sept 3rd: Alex purchased material for building 5 tables, each set of material cost her 100€. She paid in cash. 4. Sept 20th: Alex sold her first table to a customer for 1000€. The customer paid in cash. By the end of the month the machine depreciated by 1000€. By September 30th Alex had 350€ worth of inventories in her warehouse. The rent for the office in September was 500€. She would pay the rent to the landlord in October 2017. a. Record these transactions in the accounting equation.

Question 2

Tame Food Delights Limited produces cat food for the retail market. The production process

involves two stages: mixing and baking. Manufacturing costs comprise of materials, which are

added at the start of the process, and conversion costs (labour and overheads), which are

incurred evenly throughout production. The following details relate to the mixing process for

the month of May:

Degree of completion                        Cost ($)

Opening WIP (39,000 kgs)

- Materials                                                                   100%                                       67,350

- Conversion costs                                                      60%                                         12,045

Materials input and Costs incurred

- Materials (630,000 kgs)                                                                                           837,900

- Conversion costs                                                                                                      396,240

Normal spoilage 5% of materials input

Output 615,000 kgs

Closing WIP (22,500 kgs)

- Materials                                                                   100%

- Conversion costs                                                      80%

Required:

1. Briefly outline the circumstances where process costing may be suitable as a method of valuing production.

(b) For the month of May prepare the mixing process account using:

(i) The first in first out (FIFO) method of valuing inventory.                       

(ii) The weighted average (WA) method of valuing inventory.                    

In relation to process costing, give TWO reasons why the weighted average method valuing inventory may be preferable to the FIFO method

Write a program that loops, prompting the user for their full name, their exam result (an integer between 1 and 100), and then writes that data out to file called ‘customers.txt’. The program should check inputs for validity according to the following rules:

• First and last names must use only alphabetical characters. No spaces, hyphens or special characters. Names must be less than 20 characters long.
• Exam result (an integer between 1 and 100 inclusive)

The file should record each customers information on a single line and the output file should have the following appearance.

Nurke Fred 58

Cranium Richard 97

Write a second program that opens the ‘customers.txt’ file for reading and then reads each record, splitting it into its component fields and checking each field for validity.

The rules for validity are as in your first program, with the addition of a rule that specifies that each record must contain exactly 3 fields.

Your program should print out each valid record it reads.

The program should be able to raise an exception on invalid input, print out an error message with the line and what the error was, and continue running properly on the next line(s).

Mrs. Watson came in through the front door of her house with an armful of groceries. She put the bag down on the kitchen counter and called to her husband. “Herb, I’m home! Are you ready for lunch?” She didn’t get an answer,
so she walked to the living room and found Mr. Watson lying on the floor. “Herb! Are you okay?” she asked as she grabbed his shoulder. Mr. Watson responded weakly while clutching his chest. Mrs. Watson frantically called 911. It only took EMS a few minutes to arrive and the paramedics transported Mr. Watson to the hospital. Upon admission to the hospital, Mr. Watson’s vital signs were recorded as follows:

1. Which of Mr. Watson’s vital signs and lab values are abnormal? Are the levels above or below normal?

2. What is cardiac output? Use Mr. Watson’s vitals above to determine what is happening to his cardiac output.

Mr. Watson was admitted to the hospital with chest pains and shortness of breath. His wife was panicked since her 72 year-old husband has a history of heart disease. After examination and an echocardiogram, Dr. Collins determines that Mr. Watson’s left posteromedial papillary muscle is damaged, resulting in valve prolapse.   

3. What is an echocardiogram?

4. Explain why valves are critical to proper blood flow through the heart.

5. What is the function of papillary muscles? Which of Mr. Watson’s valves is affected by this damage?   How does this damage disrupt blood flow?

6. Revisit your answer to question #2. Specifically, how does Mr. Watson’s valve prolapse affect his cardiac output? How does this impact his BP and heart rate?

Mrs. Watson was very upset with the news of her husband’s condition. As the day progressed, she noticed that Mr. Watson’s breathing was increasingly difficult. He could barely speak without losing his breath. Mrs. Watson called the nurse to her husband’s room. “My husband can’t breathe! What is wrong? I thought he had a heart attack not a respiratory condition!” Nurse Dan auscultated the patient’s chest listening to Mr. Watson’s respirations, which were rapid and wet, producing rales (wet breath sounds) or crackling sounds. Nurse Dan calmly informed Mrs. Watson, “I’m sorry. Your husband’s condition is worsening. The damage to his heart is causing his respiratory problems.”

7. The circulatory system consists of two circuits. The left side of the heart receives blood from which circuit?

8. How is the pulmonary circuit affected by Mr. Watson’s valve prolapse? Is pressure in the pulmonary circuit increasing, decreasing or staying the same?

9. Explain how this change in pulmonary blood pressure affects capillary filtration in the lungs.

10. If Mr. Watson’s tricuspid valve had failed instead, what symptoms would be different and why?

Mr. Watson underwent valve replacement surgery successfully and was discharged from the hospital with no further complications. Often, patients’ valvular deficiencies don't require surgery, only medications to control their symptoms and alleviate stress on the heart. Three possible medical treatments are listed below. Please discuss the mechanism of action for each medication and why it might be a useful medication for mitral valve deficiency.   Please also discuss at least one side effect of each medication. Explain why the drug causes that side effect.

a. beta blockers

b. ACE Inhibitors

c. anticoagulants “blood thinners” (warfarin)

Which of the following statements regarding a 30-year monthly payment amortized mortgage with a nominal interest rate of 8% is CORRECT?

.

The manufacturer of an MP3 player wanted to know whether a 10 percent reduction in price is enough to increase the sales of its product. To investigate, the owner randomly selected eight outlets and sold the MP3 player at the reduced price. At seven randomly selected outlets, the MP3 player was sold at the regular price. Reported below is the number of units sold last month at the sampled outlets. Regular price 134 125 88 113 143 129 96 Reduced price 126 133 152 132 113 107 116 112 At the .010 significance level, can the manufacturer conclude that the price reduction resulted in an increase in sales? Hint: For the calculations, assume the "Reduced price" as the first sample.
