Question 895858: Demetra has taken nine quizzes in an environmental science class, and the mean of her score is 81. The syllabus states that the two lowest quiz scores will be dropped. If her lowest scores are 57 and 62, what is the mean to the nearest whole number of her seven remaining scores? Answer by JulietG(1812) (Show Source):
You can put this solution on YOUR website! 9 quizzes at 81 = 729 points total
Drop the two lowest.
729 - 57 - 62 = 610 points total
Those 610 points are now for 7 quizzes instead of 9
Divide 610 by 7 to find the new mean.
610/7 = 87 (87.142851428514285... rounded to 87)
