Question 774256: Gabe received the following scores on 4 tests. 87,92,95,82. What must he get on the next test to have an average of 90? Answer by Cromlix(4381) (Show Source):
You can put this solution on YOUR website! The average of 5 tests = 90%
Total scores on 5 tests = 5*90 = 450
Total of scores for 4 tests = 356
450 - 356 = 94.
Gabe would require to score 90 on
his fifth test to achieve an average
of 90%
Hope this helps.
