"Texas christian university admits 3 out of every 4 students who apply to attend the school if 2,040 freshmen apply how many students will not be able to apply"
75% acceptance rate
x = freshmen accepted
x/2040 = 75/100, or x/2040 = 3/4
cross multiply
2040(3) = 6120
4(x) = 4x
input values into equation
4x=6120
divide both sides by 4
x = 1530
therefore, if 2040 apply, and 1530 get accepted, then 510 aren't accepted.
After finishing, I realized that the question is invalid. An uncountable number of people can choose not to apply.
