43. A college admissions officer predicts that 20 percent of the students who are accepted will not attend the college.  According to this prediction, how many students should be accepted to achieve a planned enrollment of x students?

这里x是students who are accepted to attend the college？谢谢大牛。

嗯嗯，懂了，真是通俗易懂啊

直观点说就是，蓝色部分＝收到offer的学生。
因为20％收到offer的学生不会accept offer，所以需要发（1／0。8）＝125％＊planned enrollment份offer
希望能帮助到。
