Grading Calculations
You are not doing as well as you had hoped in one of your classes. So, you want to
figure out the minimum grade you need on the final exam to receive the semester grade
that you want. Is it still possible to get an A? How would you explain your calculations
to a classmate?

There are five tests each semester (four exams and one final). Given the percentage
scores on the first four exams, determine if it is possible for you to get an A with
your score on the final. Remember, the maximum possible score is 100%.14Z²
