the president of aerospace innovators, an aerospace design firm, is given an internal report titled 2011 revenues and expenses, commercial flight division, aerospace innovators.
the company has three divisions, each specializing in designing aircraft to meet the needs of a particular industry:

• military operations division
• helicopters
• supersonic planes
• missiles
• transports
• commercial flight division
• propeller airplanes
• jet airplanes
• gliders
• float planes
• space exploration division
• rockets
• space shuttles
• space stations
• satellites

which of these are likely to be topics that will be part of the main section titles for this report?
☐ 2011
☐ military operations division
☐ commercial flight division
☐ supersonic planes
☐ float planes

which of the following pieces of information are likely going to be present in the report?
☐ the total expenses for float planes in 2011
☐ the total revenues from military operations division in 2011
☐ the commercial flight division’s total revenues in 2011
☐ the total revenues for aerospace innovators in 2011

which of the following will you be able to calculate from information in the report?
☐ the fraction of the total revenues from the commercial flight division that were generated from designing jet airplanes in 2011
☐ the sum of what was spent on projects on propeller airplanes and on projects on supersonic planes in 2011
☐ the difference in 2011 revenues from satellites and from helicopters
☐ the difference between the company’s 2011 revenues received from projects on propeller airplanes and from projects on supersonic planes
☐ the sum of 2011 revenues generated by sales of gliders and sales of propeller airplanes

Explanation:

For the first question: The report is titled for 2011 Revenues/Expenses of the Commercial Flight Division, but the company's structure is organized by main divisions. 2011 is the time frame, not a section title; the sub-categories (Supersonic Planes, Float Planes) are too narrow. The main sections would align with the company's core divisions.
For the second question: The report covers the Commercial Flight Division's 2011 finances, so it will include its total revenues. It will also include granular data for sub-units like Float Planes (expenses). The company-wide total revenues and full Military Division revenues are outside the report's stated scope.
For the third question: The report focuses on the Commercial Flight Division, so only calculations using data within this division are possible. Cross-division sums/differences are unavailable, but the fraction of the division's revenue from jet airplanes can be calculated using the division's total revenue and jet airplane revenue data.

Answer:

First Question:

• Military Operations Division
• Commercial Flight Division

Second Question:

• The total expenses for Float Planes in 2011
• The Commercial Flight Division's total revenues in 2011

Third Question:

• The fraction of the total revenues from the Commercial Flight Division that were generated from designing jet airplanes in 2011
• The sum of 2011 revenues generated by sales of gliders and sales of propeller airplanes
