Here, we are required to determine how far the student described in the question is from the average.
The correct answer is Choice C: |x – 78|.
According to the question; the student received a score of x%.
As such, x% may either be greater or lesser than the average score, 78%.
- <em>To determine how far the student's score is from the average, we need to take the difference between the student's score and the average score; i.e. (x - 78)</em>
- <em>This difference may however be negative: As such, there's need to take the absolute value of (x - 78) which yields |x – 78|.</em>
<em>Therefore, the expression that could be used to determine how far the student’s score is from the average is; |x – 78|</em>
