If I have an 85% class average and my final is worth 20% of my grade.
\n" ); document.write( " What grade do I have to get in order to keep at least an 83 average in the class.
\n" ); document.write( ":
\n" ); document.write( "let x = the grade required to have an 83 average
\n" ); document.write( "final is 20% which is 1/5 of your grade, that means 4/5 is class average
\n" ); document.write( " $\"%28%284%2885%29+%2B+x%29%29%2F5+=+83\"$
\n" ); document.write( "multiply both sides by 5, do the math
\n" ); document.write( "340 + x = 415
\n" ); document.write( "x = 415 - 340
\n" ); document.write( "x = 75% will give you and 83 \n" ); document.write( "

\n" );
