Math Question

[Bruw]

Basically in my math course my exam counts as %20 of your grade. I have. 67.7% in the class. Whats the lowest i can get on the exam to pass with a 60%?

You need around 29%. Good luck with your exams!

You need atleast a 29.2%

 

Moved to homework help, I think it's much more appropriate.

Do this:
[(your mark now) X 0.8 + (your mark on exam)] X 0.2

This will give you the result mark, as in final term mark.

How to solve:

(current percent) * (percent it is worth) + (unknown percent) * (percent worth) = final percent.

so solve for unknown percent:
in your case...

(67.7*0.8) + x (0.2) = 60

were x = unknown percent (or percent needed to get 60 final)

solve for x

x(0.2)= 60 - (67.7*0.8)

x(0.2)= 5.84

x = 5.84/0.2

x = 29.2

So you need at least 29.2% on your final xam to finish off class with 60% avarage.
