Question 916134: Fred has scores of 85, 91, 78, and 82. How much must he score on the fifth test to average 85 on all five? Answer by JulietG(1812) (Show Source):
You can put this solution on YOUR website! Assuming all the tests are worth the same 100 points, he will need 85*5 points, or a total of 425 points.
He already has 85+91+78+82 = 336. His final test needs to be 425 - 336, or an 89.
