Question

If I have a 85 in my class and a 74-84 is a B. And the last thing I need to take is my final which is worth 34%, what do I need to make sure I stay in the B range?

Answer 1

100 - 34 = 66 meaning 66% of your mark has already been determined

let x = mark on final

85(0.66) + 0.34x = 74

Answer 2

Thank you
