<PRE><B>Question 455638</B>
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%
:
{{{(7(91)+3x)/10}}} = 93
multiply both sides by 10
7(91) + 3x = 930
637 + 3x = 930
3x = 930 - 637
3x = 293
x = {{{293/3}}}
x = 97.67%
