You can put this solution on YOUR website!
Since you wnt to know your percent for the right ones (let the percent for correct ones be x)
\n" ); document.write( "First:42-14=30
\n" ); document.write( "next 42 correct means 100 percent
\n" ); document.write( "30 correct we need to find the percent.
\n" ); document.write( "42--------100
\n" ); document.write( "30--------x\r
\n" ); document.write( "\n" ); document.write( "So cross multiply:
\n" ); document.write( " $\"42x=30+x+100\"$
\n" ); document.write( " $\"x=30+x+100%2F42\"$
\n" ); document.write( " $\"71.43\"$
\n" ); document.write( "Your percent is 71.43% \n" ); document.write( "

\n" );
