Question 851210: You have an average of 80 on six quizzes. The teacher announces your next test grade will be averaged with the quizzes. You get a 90. What is your quiz average now? Answer by JulietG(1812) (Show Source):
You can put this solution on YOUR website! Through 6 quizzes, you have an average of 80. 480/600 points.
On the next quiz, you get a 90. Now you have 480+90/600+100
570/700 = 81.4
