\n" ); document.write( "\n" ); document.write( "\"and a ruler\" ___ r\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"together cost $4\" ___ c + r = $4\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"The compass costs .90 more than the ruler\" ___ c = r + $.90
