If I have a grade of 87% worth 50% of my grade, a grade of 83.33 worth 25% of my grade and a grade of 95% worth 15% of my grade and quizzes are worth 10%. My total grade is 87. 31%, what do I need to get at least 95%?
\n" ); document.write( ":
\n" ); document.write( "90% or 9/10th of the grade = 87.31
\n" ); document.write( "let x = av grade on the quizzes, the remaining tenth of your grade
\n" ); document.write( ":
\n" ); document.write( " $\"%28%289%2887.31%29%2Bx%29%29%2F10\"$ = 95
\n" ); document.write( "multiply both sides by 10
\n" ); document.write( "785.79 + x = 950
\n" ); document.write( "x = 950 - 785.79
\n" ); document.write( "x = 164.21, which is more than 100%, there is no way you can raise it to 95%
\n" ); document.write( " \n" ); document.write( "

\n" );
