Question 768104: On the first 5 quizzes of his physics class, Daniel got an average score of 85.
What does he need on the next quiz to have an overall average of 87? Answer by Cromlix(4381) (Show Source):
You can put this solution on YOUR website! 5 quizzes average score = 85
Total scores = 85 * 5 = 425
Total scores = 87 * 6 = 522
So Daniel requires a score of(522 - 455)
= 67 to attain an average of 87 with
the 6 quizzes.
Hope this helps.
