    There are 33 parents attend the school brass band competition

    Step-by-step explanation:

    The attend = Children + Teachers + Parents

    The number of attend = 272

    The number of children who attend = 223

    The number of teachers who attend = 16

    The number of parents who attend = x

    Substitute the numbers in the equation above

    272 = 223 + 16 + x

    223 + 16 = 239

    272 = 239 + x

    Subtract 239 from both sides

    33 = x

    x represents the number of the parents who attend
