A) 1.05x
B) 1.1 x
C) 1.2 x
D) 1.25 x
E) 1.8 x
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: [spoiler]# accepted = 1.25x[/spoiler]
Answer:
D
