Question 899524: You have one more math test.
Here are your present scores:
89 , 92 , 78 , 83 , 83 .
What score must you get to raise the mean to 87? Answer by swincher4391(1107) (Show Source):
You can put this solution on YOUR website! (89+92+78+83+83+x)/6 = 87
Multiply both sides by 6.
89+92+78+83+83+x = 522
425 + x = 522
Subtract 425
x = 97
