I received a $\frac {43}{70}$ on an exam and my professor gave us the following curve equation to calculate our adjusted grade, I was wondering how I calculate it?

Here is the curve equation: $2+\frac {1*(x-40)}{12}$

Thanks!

    What does $x$ represent? – 2017-02-06

You plug in 43 for $x$ to get $$ g = 2 + \frac{1*(43 - 40)}{12} = 2 + \frac{3}{12} = 2 + \frac{1}{4} = 2.25. $$

    is 2.25 what i add onto my grade? or what is 2.25's significance? – 2017-02-06

    We don't know. That's something you ask your instructor. – 2017-02-06

    By the way, both the "2" and the "1 *" seem very unlikely to me. When you need to multiply something by 1, you usually just omit the multiplication, for instance. Was there perhaps a transcription error? – 2017-02-06
