    total number of red marbles=18 marbles

    Step-by-step explanation:

    Step 1

    Express the fraction of each type of marble as a function of the total number of marbles as shown;

    Let;

    total marbles=x

    red marbles=3 / (3+4) = 3/7x

    blue marbles=4/7 x

    But x=42 marbles

    The total number of marbles for each type can be expressed as;

    total number of red marbles=fraction of red marbles*total number of marbles

    where;

    fraction of red marbles=3/7 x

    total number of marbles=42

    replacing;

    total number of red marbles = (3/7) * 42=18 marbles

    total number of blue marbles=fraction of blue marbles*total number of marbles

    where;

    fraction of blue marbles=4/7 x

    total number of marbles=42

    replacing;

    total number of blue marbles = (4/7) * 42=24 marbles
