Question: In a group of five students who took the same test, four of the scores were 85 , 92 , 81 , and 95 . If the average of the five students was 89 , what was the score of the fifth student?
The sum of the scores for the five students can be found by multiplying the average score by the number of students. So, 89 * 5 = 445 To find the score of the fifth student, subtract the known scores from the total. 445 (total of all scores) - 85 - 92 - 81 - 95 = 92 So, the fifth student's score was 92.
