Answer: 280

Step-by-step explanation:

                  Quantity   X    Cost    =  Money Received

Adult:               x                   3                   3x          

Children:       500-x              2            2(500 - x) = 1000 - 2x


Adult = Children + 400

  3x   =  1000 - 2x + 400

  3x   =   1400 - 2x

  5x   =   1400

    x    =    280
