    Thanks for your help. It is much appreciated. This is a year 9 maths problem. I am under the impression that it can be solved using simultaneous equations. Do you know if it can be solved using simultaneous equations and if so, how?

    PS: Why shouldn't I upload Word files?

    Thanks.

    You shouldn't upload Word documents because it could contain viruses or other dangerous material that other members don't know about.
    Also there is no point in attaching a Word document while you can just copy/paste the text directly into here.


    "The school play was attended by 550 people and the revenue from ticket sales was $4980. If each adult paid $12 and each student paid $8, find how many adults and students attended the play."


    Suppose adult = x
    and student = y

    Therefore:

    \mbox{$}12x + \mbox{$}8y = \mbox{$}4980
    $12 * number of adults + $8 * number of students = $4980 in total.

    x + y = 550~ \mbox{people}
    The number of adults + the number of students = 500 in total.

    You can use the substitition method or elimination method to solve for x and y.
