# QRB501 Case Study 2.2 and 2.2

21.1 Contemporary Wood Furniture Charles Royston was checking the year-end balances for his wood furniture manufacturing and retail business and was concerned about the numbers. From what he remembered, his debts and accounts receivable were higher than the previous year. Rather than get worked up over nothing, he decided he would gather the information and make a comparison. For December 31, 2011, the business had current assets of: \$1,844 cash, \$11,807 accounts receivable, and \$9,628 inventory. Plant
and equipment totaled \$158,700. Current liabilities were: accounts payable \$13,446; wages payable \$650; and property and taxes payable \$4,124. Long-term debt totaled \$92,800 and owner’s equity \$70,959. By comparison, for December 31, 2010, the business had current assets of: \$3,278 cash;
\$6,954 accounts receivable; \$17,417 inventory. Plant and equipment totaled \$144,500. Current liabilities
were: accounts payable \$9,250; wages payable \$1,110; property and taxes payable \$3,650.
Long-term debt totaled \$75,800; and owner’s equity \$82,339.

1. Construct a comparative balance sheet for Contemporary Wood Furniture for year- end 2010 and 2011, including a vertical and horizontal analysis of the comparative balance sheet. Express percent to the nearest tenth of a percent.
2. Calculate the current ratio and the total debt to total assets ratio for 2010 and 2011.
3. Overall, what does your analysis mean? Is Charles correct to be concerned about these numbers? Explain.

21.2 Balanced Books Bookkeeping Jessica and David are student interns at Balanced Books Bookkeeping. They have taken several business math and accounting classes and are now applying what they have learned to real-life situ- ations. They enjoy their internship, but they are sometimes surprised by the assignments they are given. Luckily, they work together, so they share the assignments and learn from each other. Their most recent assignment is to take a listing of accounts provided by one of Balanced Books’ clients and turn them into a balance sheet and income statement. David suggests that their client might ap- preciate it if they also performed a vertical analysis of each statement. Jessica suggests that they should also compute the current ratio and the acid-test ratio.

1. Create the financial statements for December 31, 2011, depict them in vertical format, and compute the current and acid test ratios. Account title Amount Account title Amount Cash \$4,000 Accounts payable \$3,500 Depreciation 2,000 Merchandise inventory 15,000 Carlton, equity 34,500 Accounts receivable 6,000 Cost of goods sold 85,000 Net sales 120,000 Rent expense 15,000 Insurance payable 500 Wages payable 1,500 Equipment 15,000 Utilities 6,500 Wages 8,000 Miscellaneous expenses 1,500 write a paragraph or so summarizing what you “took-away” from Case Study 21-2, p. 769.

# Case Study

• Write an imaginary case study for your hypothetical patient.(about 2 pages)
o Explain how the patient moved through the healthcare delivery system.
o With respect to the costs you calculated last week, describe how the patient will pay for the cost of treatment.
• Analyze the healthcare delivery system as illustrated in this case. What problems did you notice? Would some people find it difficult to pay for treatment? Are there areas where treatment for this illness is unavailable or unaffordable to the common person?
• Incorporate the feedback you have received from your instructor for all the tasks of the project topic you selected, including the corrective feedback or suggestions for more information.
• Ensure that your completed project meets all of the expectations of each week’s tasks.
• Combine what you have developed in Weeks 2–5 into a single 14- to 16-page Microsoft Word document, applying appropriate headings and formatting to make it one complete document, including works cited or referenced on the final page of the document. Cite all references in APA format.

# Unit III Article Review

Unit III Article Review
In this unit, you learned about the doctrine of respondeat superior, which states that an employer may be held liable for
the actions of his/her employees. For this assignment, you will choose a peer-reviewed article to review regarding this
doctrine as it relates to the healthcare industry. Use the databases within the CSU Online Library, or use another

articles that contribute to the industry. The authors of these articles are researchers and professionals who have shared or
experimented with ideas that demonstrate potential to improve the industry. As a professional in the industry, it is in your
best interest to review the literature and trends. This provides you with the opportunity to read about what was successful
and how it was accomplished. Plus, it allows you to analyze what was unsuccessful, how you can improve it or at least
how you can avoid repeating the mistakes of others. Use these skills to contribute to research papers and other scholarly
writings. If you have not already, hopefully, you will contribute to the industry by publishing an article and sharing with your
community of peers.
As you read the article you choose for this assignment, consider the following questions: How could the topic of this
article apply to your personal or professional life? How could it apply to an organization you have observed?
The article you choose must meet the following requirements:

Explain how the doctrine of respondeat superior was depicted in your article. Was it discussed in a positive or·
negative light?
Explain if it is logical to judge an employer for the actions of an employee? Why or Why not?·
