Question

The more you study for a certain exam, the better your performance on it. If you
study for 10 hours, your score will be 65%. If you study for 20 hours, your score will
be 95%. You can get as close as you want to a perfect score just by studying long
enough. Assume your percentage score, p (n), is a function of the number of hours, n,
that you study in the form p(n)=an+b/
cn+d. If you want a score of 80%, how long do
you need to study?
