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?

Answer 1

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.

Answer 2

Aww.. :(

Oh well, I'll be happy with an 88!

Thanks Henry :)
