\n" ); document.write( "Let x = student tickets sold
\n" ); document.write( "then
\n" ); document.write( "150-x = non-student tickets sold
\n" ); document.write( ".
\n" ); document.write( "Since we know the total revenue, we get
\n" ); document.write( "930 = 5x + 8(150-x)
\n" ); document.write( "930 = 5x + 1200 - 8x
\n" ); document.write( "930 = 1200 - 3x
\n" ); document.write( "930 + 3x = 1200
\n" ); document.write( "3x = 270
