\n" ); document.write( " $\"N+=+50+-+D\"$
\n" ); document.write( "Therefore
\n" ); document.write( " $\"5%2850+-+D%29+%2B+10D+=+350\"$
\n" ); document.write( " $\"250+-+5D+%2B+10D+=+350\"$
\n" ); document.write( " $\"5D+=+100\"$
\n" ); document.write( " $\"D+=+20\"$
\n" ); document.write( " $\"N+=+50+-+D\"$
\n" ); document.write( " $\"N+=+50+-+20\"$
