Question 851060: out of 5 games the average is 88. Out of 6 games the average is 90. What was the score on the 6th game?
Answer by JulietG(1812)   (Show Source):
You can put this solution on YOUR website! Assuming 100 points per game,
In 5 games, the score is 5*88 = 440
For the average to be 90 in 6 games, the total would need to be 90*6 = 540. If you already have 440 points through the first five games, you'll need 540-440, or 100, to average 90.
