Question 705387: Jaime has test scores of 78, 84, 89, 92, and 76. What score will she need to get on the 6th test to ensure an average of 85%? Answer by solver91311(24713) (Show Source):
In order for the average of 6 scores to be 85, the sum of all 6 scores must be 6 times 85. Subtract the sum of the first 5 scores from 6 times 85 to get the score required for 85 in 6.
