The question asks for the score needed on the final to achieve an overall course grade of 85% in the Excel file kirkwood.xlsx, using the Goal Seek feature in the Goal Seek worksheet. Since the numerical outcome depends on the specific grade components and their weights in that workbook, we cannot produce a definitive number here without accessing the file.

What you should do to find the answer yourself:
1) Identify the structure of the overall grade in the Goal Seek worksheet. Look for the cell that represents the final course grade (the target you want to hit, e.g., a cell showing the calculated average or final percentage).
2) Find the cell that represents the final exam score (the variable you can change to influence the final grade). This is the value you would adjust with Goal Seek.
3) Write/confirm the formula that links the final exam score to the overall course grade. Typically, this is a weighted average: FinalGrade = (Component1 * Weight1) + (Component2 * Weight2) + ... + (FinalExamScore * FinalExamWeight). Ensure you understand which components (homework, midterms, quizzes, etc.) and their weights contribute to the total.
4) Use Goal Seek:
   - In Excel, go to Data > What-If Analysis > Goal Seek.
   - Set cell: choose the overall course grade cell (the target 85%).
   - To value: enter 85 (the desired final grade).
   - By changing cell: select the final exam score cell (the variable you will adjust).
   - Run the tool and let Excel compute the required final exam score to achieve 85%.
5) Review the result:
   - If the computed final exam score is a reasonable number, round to a whole number as the instructions require (e.g., 10.35 → 10, 10.51 → 11).
   - If the result is outside permissible ranges (e.g., negative or above maximum possible score), re-check the weights and the formula to ensure there isn’t an error in the setup, since it would be impossible to reach 85% with the given parameters.
6) Validate by re-checking the final grade calculation with the rounded value to confirm it meets or approximates 85% as expected.

Notes on potential pitfalls:
- The final grade might depend on more than one adjustable item; ensure that Goal Seek is indeed pointing to the final exam score cell and not to a different input.
- If the worksheet uses different sections or extra credit, verify that all such factors are correctly included in the final grade formula.
- If the workbook uses a non-standard rounding rule, apply the same rule when interpreting the final numeric result (the instruction says to round to a whole number).

In summary, the exact numeric answer cannot be provided here without opening kirkwood.xlsx. Follow the outlined steps in Excel to determine the precise final exam score needed to reach 85%, then apply the specified rounding rule to present the final value.
