Question 906163: At the end of quarter 1, Bryan wants to have a 90% average. His first four test scores were 94, 86, 87, and 89. There is one more test. What is the minimum he needs to score to get his 90% for the quarter? Answer by AlgebraLady88(44) (Show Source):
You can put this solution on YOUR website! The minimum Bryan would need to score would be
(94 + 86 + 87 + 89 + x) / 5 = 90
94 + 86 + 87 + 89 + x = 450
356 + x = 450
x= 94
Bryan would need to score 94 % on the 5th test in order to get the 90 % average
