Question 583737: If I have a 63% in a class and my final test is worth 20% of my grade. What will I have to score on the test in order to maintain a 63% in class?
Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website!
0.8*0.63 + 0.2x = 0.63
0.504 + 0.2x = 0.63
0.2x = 0.63-0.504
0.2x = 0.126
x = 0.126/(0.2)
x = 0.63
So you need to score a 63% to maintain a 63%. Scoring anything higher will bring your overall grade higher.
