Question 816929: If my semester average now is 61, finals are worth 10% percent of my grade. What will I need to make on my final to make a 70? Answer by LinnW(1048) (Show Source):
You can put this solution on YOUR website! (0.9)61 + (0.1)X = 70 will give us the grade needed to have an average
of exactly 70
54.9 + 0.1x = 70
Subtract 54.9 from each side.
0.1x = 70 - 54.9
0.1x = 15.1
x = 151
So we need a score of 151 on the final to have an average of 70.
