How Much these two pay.
\n" ); document.write( "n Anna
\n" ); document.write( "m Michael\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "m+n=20 and n-m=2; no pay data was given about Elvin. This person is not part of the problem description.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "n=m+2;
\n" ); document.write( "m+m+2=20
\n" ); document.write( "2m+2=20
\n" ); document.write( "m+1=10
\n" ); document.write( "m=9 and n=11.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Michael pays $9 and Anna pays $11.
\n" ); document.write( "The quantity to pay is accounted according to the description. Elvin pays nothing.
\n" ); document.write( "
\n" );
