Let x: number of student tickets sold
\n" ); document.write( " 400-x: number of adult tickets sold\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Since the cost of a student ticket is $2, and an adult ticket costs $3:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2x: money earned from student tickets
\n" ); document.write( "3(400-x): money earned from adult tickets\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Equation: 1050 = 2x + 3(400-x)
\n" ); document.write( " 1050 = 2x + 1200-3x
\n" ); document.write( " 1050 = -x + 1200
\n" ); document.write( " 1050 - 1200 = -x
\n" ); document.write( " -150 = -x
\n" ); document.write( " -x = -150
\n" ); document.write( " x = 150\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "400 - 150 = 250\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Student tickets: 150
\n" ); document.write( "Adult tickets: 250\r
\n" ); document.write( "
