    Step-by-step explanation:

    Alyssa has 4 green marbles out of 16.

    % Green = 4/16 * 100 % = 25 %

    So, Carla's 10 green marbles are 25 % of her total.

    Her total number of marbles is 10 * (100%/25 %) = 40 marbles.

    Total = 40 marbles

    -Green = 10 marbles

    Not green = 30 marbles
