Accepted = y
will attend = 0.8y
class = x
What is y?
If prediction is true,
Will attend = class
So, x=0.8y => y=1.25x

if you found difficulties to write the algebra , try to take a simple example, and try to avoid 100 because many times it could be true for a base 100 but then false when you use different data.

let's say we want 200 people to be enrolled, we know that the rate is 80/100 (100-20%) so now you can write :

80%X = 200
X=20000/80 = 250

so you need 250 accepted people to be sure that 200 people will be enrolled, which means that you need 250/200 = 125/100 = 1.25 more people than the enrollement objective
