A conditional percentage starts with wording that limits the group, such as “of the in-office employees.” That group is the whole for the percent, even though the table includes other employees. Add its column, find the target where the row and column meet, then use Desmos to convert part over whole to a percent. Using a department’s row total answers the reversed question.
Hints
- Hint 1
A condition limits who counts. In-office employees means the remote and hybrid columns are out. Which column gives the whole for this percent?
- Hint 2
A column total adds everyone under one heading. Read down In office, including every department. Don’t stop at Finance when finding the denominator, the number you’ll divide by.
- Hint 3
The numerator counts people meeting both descriptions: in office and in Finance. Find the cell where that row and column cross. How does that count compare with the in-office total?
Step-by-step
Use the in-office column as the whole
Step 1Find the in-office total
The phrase in-office employees limits the group, so read down that column: . Type , then in Desmos. It shows , the column total. Remote and hybrid employees don’t belong in this whole.
- Step 2
Find the part within that total
The Finance row meets the In office column at . That’s the part: employees who meet both descriptions. Divide the part by the total of the group named after “of.” So the share is . Using the Finance row total instead would answer a different question.
- Step 3
Convert the share to a percent
Type beneath the earlier lines. Desmos prints . Round to the nearest tenth, one digit after the decimal: of in-office employees work in Finance. Choice C.
