(enrollment) = 0.8*(accepted)
x = 0.8*(accepted)
(accepted) = x/0.8 = x*10/8 = 1.25x.
Answer: D.

Picking numbers would be a good way to solve this problem:
Let's say the number of students desired 'x' is equal to 100
20% of the students who are accepted will not attend. So only 80% of the students who are accepted will attend.
So we can form the question, 100 is 80% of what number:
8y/10=100
8y=1000
y=125
This tells us that 125 students need to be accepted so that there are 100 students enrolled
125=1.25(100)
Since we know x=100 then
1.25x=125
Answer choice D
