Asked by Lucina

If I have an 85% in a course, what mark would I need to raise to an 89+ if my final is worth 25% of the whole course?
Answered by Henry
0.75*85 + 0.25*F = 89
63.75 + 0.25F = 89
0.25F = 89-63.75 = 25.25
F = 101 = Finals score.
Cannot be done!

0.75*85 + 0.25*100 = 88.75% = Max. possible score.
