    164 kids

    165 adults

    Step-by-step explanation:

    First you need to make two equations

    kids = x

    adults = y

    first equation = x+y=329

    second equation = 1.5x + 4y = 906

    solve by substitution

    x = 329 - y

    1.5 (329 - y) + 4 y = 906

    493.5 - 1.5y + 4y = 906

    combine like terms

    2.5y = 412.5

    y = 165

    plug back into one of the equations

    x + 165 = 329

    x = 164
