Explanation / Answer
Average of all your assignment grades = ( 100(15) + 96 + 92 + 91 + 88 + 82 + 80 + 71 ) / 22
= 2100 / 22
Assignments grade = 95.455 %
Midterm grade = 65%
Current grade = [ (50)x(95.455) + (25)x(65) ] /(50+25)
Your current grade = 85.30 %
Let Final test grade be X.
70% = [ (50)x(95.455) + (25)x(65) + 25(X)] / 100
70 = 63.977 + 0.25X
X = 24.09 % [This is for getting 70%]
I think you can do better than this for sure.
For getting 80%,
80 = 63.977 + 0.25X
X = 64.09% [This is for getting 80%.]
