If i have an 91% in my math class and i am about to take an exam that is 30%
(330 points) of my grade,
what percent do i need to make on the final to get an A in the class? BTW an A=93%
:
Let x = exam grade required to get a grade of 93%
:
%287%2891%29%2B3x%29%2F10 = 93
multiply both sides by 10
7(91) + 3x = 930
637 + 3x = 930
3x = 930 - 637
3x = 293
x = 293%2F3
x = 97.67%
