If 20% of those accepted don't enroll, then 100%-20% = 80% of those accepted actually enroll.

Setting A = accepted students and X = enrolled students, the above is:

(80/100)* A = X

With the goal of enrolling X students, the number of students needing to be accepted is



A= X*(100/80) = X * (5/4)

= 1.25X, D

20 percent of the students who are accepted will not attend the college
In other words, 80 percent of the students who are accepted WILL ATTEND the college.
In other words, 4/5 of the students who are accepted WILL ATTEND the college.
We can write (4/5)(# accepted) = # who attend

Let x = # of students who attend.
We get the equation: (4/5)(# accepted) = x
Multiply both sides by 5/4 to get: # accepted = (5/4)x
Rewrite as: # accepted = 1.25x

Answer: D

Cheers,
Brent
