Cincinnati, Ohio, also known as the Queen City, has a population of approximately 298,000 and is the third largest city in the state of Ohio. The Cincinnati metropolitan area has a population of about 2.2 million. The city is governed by a mayor and a nine-member city council. The city manager, who is responsible for the day-to-day operation of the city, reports to the mayor and city council. The city manager recently created the Office of Performance and Data Analytics with the goal of improving the efficiency of city operations. One of the first tasks of this new office is to review the previous year’s expenditures. The file QueenCity contains data on the previous year’s expenditures, including the following:
Department: The number of the department incurring the expenditure
Department Description: The name of the department incurring the description
Category: The category of the expenditure
Fund: The fund to which the expenditure was charged
Expenditure: The dollar amount of the expense
Table 2.21 shows the first four entries of the 5427 expenditures for the year. The city manager would like to use this data to better understand how the city’s budget is being spent.

Answer to Problem 3CP
The following table represents the total amount of expenditure by category and percentage of total expenditures by category:
Category | Total expenditure | Percentage of total expenditure |
Capital | $198,365,854 | 29.98% |
Payroll | $145,017,555 | 21.92% |
Debt service | $86,913,978 | 13.14% |
Contractual services | $85,043,249 | 12.85% |
Fringe benefits | $66,053,340 | 9.98% |
Fixed costs | $53,732,177 | 8.12% |

Inventory | $6,393,394 | 0.97% |
Payables | $180,435 | 0.03% |
Grand Total | $661,634,693 | 100.0% |
The bar chart for “Category” is given below:
Explanation of Solution
Calculation:
The table represents the sample of 5,427 entries and the annual expenditures for queen city (City C and City O) for the year. The five types of variables present in the data are department serial number, department description, category name, fund, and expenditure.
From the data set, the variable “Category” consists of nine entities, namely capital, payroll, debt service, contractual services, fringe benefits, fixed costs, materials and supplies, inventory, and payable.
Therefore, the following table shows the amount of all nine entities’ total expenditure by category:
Category | Total expenditure |
Capital | $198,365,854 |
Payroll | $145,017,555 |
Debt service | $86,913,978 |
Contractual services | $85,043,249 |
Fringe benefits | $66,053,340 |
Fixed costs | $53,732,177 |
Materials and supplies | $19,934,710 |
Inventory | $6,393,394 |
Payables | $180,435 |
Grand Total | $661,634,693 |
The percentage for capital is calculated as the ratio of total expenditure for capital to the grand totals of all categories.
The following table shows the percentage of amount of all nine entities’ total expenditure by category:
Category | Total expenditure | Percentage of total expenditure |
Capital | $198,365,854 | 29.98% |
Payroll | $145,017,555 | 21.92% |
Debt service | $86,913,978 | 13.14% |
Contractual services | $85,043,249 | 12.85% |
Fringe benefits | $66,053,340 | 9.98% |
Fixed costs | $53,732,177 | 8.12% |
Materials and supplies | $19,934,710 | 3.01% |
Inventory | $6,393,394 | 0.97% |
Payables | $180,435 | 0.03% |
Grand Total | $661,634,693 | 100.0% |
Software procedure:
Step-by-step software procedure to obtain the bar chart for category using EXCEL software:
- In Excel sheet, enter Category in one column and Percentage of total Expenditure in another column.
- Select the data, and then choose Insert > Insert Column Bar Charts.
- Select Clustered Column under More Column Charts.
Output using the EXCEL software is given below:
From the obtained table and bar chart, it can be observed that the sum of capital expenditures and payroll contributes 50% of all expenditures.
Also, the total expenditures are over $660 million. Debt service seems to be high, and it is found to be over 10% of total expenditures.

- Cholesterol Cholesterol in human blood is necessary, but too much can lead to health problems. There are three main types of cholesterol: HDL (high-density lipoproteins), LDL (low-density lipoproteins), and VLDL (very low-density lipoproteins). HDL is considered “good” cholesterol; LDL and VLDL are considered “bad” cholesterol. A standard fasting cholesterol blood test measures total cholesterol, HDL cholesterol, and triglycerides. These numbers are used to estimate LDL and VLDL, which are difficult to measure directly. Your doctor recommends that your combined LDL/VLDL cholesterol level be less than 130 milligrams per deciliter, your HDL cholesterol level be at least 60 milligrams per deciliter, and your total cholesterol level be no more than 200 milligrams per deciliter. (a) Write a system of linear inequalities for the recommended cholesterol levels. Let x represent the HDL cholesterol level, and let y represent the combined LDL VLDL cholesterol level. (b) Graph the system of inequalities from part (a). Label any vertices of the solution region. (c) Is the following set of cholesterol levels within the recommendations? Explain. LDL/VLDL: 120 milligrams per deciliter HDL: 90 milligrams per deciliter Total: 210 milligrams per deciliter (d) Give an example of cholesterol levels in which the LDL/VLDL cholesterol level is too high but the HDL cholesterol level is acceptable. (e) Another recommendation is that the ratio of total cholesterol to HDL cholesterol be less than 4 (that is, less than 4 to 1). Identify a point in the solution region from part (b) that meets this recommendation, and explain why it meets the recommendation.arrow_forwardThe average monthly residential gas bill for Black Hills Energy customers in Cheyenne, Wyoming is (Wyoming Public Service Commission website).

Although most editors work in offices, a growing number now work remotely from home. The work can be stressful because editors often have tight deadlines.

ICUs are often the most expensive department in a hospital because of the specialized equipment and extensive training required to be an ICU doctor or nurse. Therefore, it is important to use ICUs as efficiently as possible in a hospital. According to a 2017 large-scale study of elderly ICU patients, the average length of stay in the ICU is 3.4 days (Critical Care Medicine journal article). Assume that this length of stay in the ICU has an exponential distribution. Do not round intermediate calculations. a. What is the probability that the length of stay in the ICU is one day or less (to 4 decimals)? b. What is the probability that the length of stay in the ICU is between two and three days (to 4 decimals)? c.
