Answer:

The widest range lies between [68,100]

Step-by-step explanation:

Given is - to receive a grade of B in the class you must average exam score between 80% and 89% for all 4 exams including the final.

So, the range of the addition of all 4 scores is -

\(80*4=320\)

\(89*4=356\)

Now given scores addition is = \(83+85+84=252\)

Now, the widest range of scores that you can get on the final exam in order to receive a grade of B can be found as :

\(320-252= 68\)

\(356-252= 104\)

So, the range lies between [68,100]
