    Let x be the number of adults.

    adult = x

    children = 500 - x

    total fund raised from the adult = $7x

    Total fund raised from the children = $4.5 (500 - x)

    Total fund raised = 7x + 4.5 (500 - x)

    7x + 4.5 (500 - x) = 7x + 2250 - 4.5x

    = 2.5x + 2250

    Ans: Total fund raised = $ (2.5x + 2250)
