What is the mean of exam scores?

The mean of exam scores is the sum of the scores divided by the number of exams taken, more like an average of all scores

Initially, average score on 4 exams is 82

average=total score/number of exams

average score on 4 exams=82

total score =unknown=assume it is

number of exams=4

82=x/4

x=4*82

x=328

In order to have an overall average score of 85, we would sum the total score of 4 exams and the fifth exam and divide by 5 exams

85=(328+y)/5

85*5=328+y

425=328+y

y=425-328

y=97
