a teacher knows that 80 percent will score no more than 5 points above or below the class average 85 percent on the test which inequality represents the test score of 80 percent of her student.

Darin is not a subject I have ever heard of.
You have not provided the optional answers.
It should look something like
80 < x < 90
Where x is the test score of 85% of the students.
