R+K=30 OR R=30-K
\n" ); document.write( "2R+5.50K=105.50
\n" ); document.write( "2(30-K)+5.50K=105.50
\n" ); document.write( "60-2K+5.50K=105.50
\n" ); document.write( "3.5K=105.50-60
\n" ); document.write( "3.5K=45.50
\n" ); document.write( "K=45.50/3.5
\n" ); document.write( "K=13 $5.50 TICKETS WERE SOLD BY KATHY.
\n" ); document.write( "30-13=17 $2.00 TICKETS WERE SOLD BY RON.
