You can put this solution on YOUR website!
Assuming you've done everything except the exam,
\n" ); document.write( "70% credit + 30% credit = Final Grade
\n" ); document.write( "\"0.7%2890%29%2B0.3%28x%29=92\"
\n" ); document.write( "\"63%2B3x%2F10+=+92\"
\n" ); document.write( "Subtract 63
\n" ); document.write( "\"3x%2F10+=+29\"
\n" ); document.write( "Multiply by 10/3
\n" ); document.write( "\"x=96%2B2%2F3\"
\n" ); document.write( "

You must get a 96⅔
