let x tickets of $12 & (300-x) tickets of & 15 were sold for a total value of $4140
\n" ); document.write( "so 12x+15(300-x)=4140
\n" ); document.write( "or 12x+4500-15x=4140
\n" ); document.write( "or 3x=4500-4140=360
\n" ); document.write( "or x=360/3=120
\n" ); document.write( "so 120 tickets of $12 & 180 tickets of & 15 were sold
