Plug in x=80. This represents the desired enrollment.
For an enrollment of 80 students, 100 must be accepted (since 20% will not attend college).
Now we plug x=80 (the desired enrollment) into all the answer choices to see which yields 100 (the number of students that must be accepted).
Only answer choice D works:
1.25*80 = 100.
The correct answer is D.
