    Answer:

    2

    Step-by-step explanation:

    Angela has a marbles.

    Brian has twice as many as Angela, so Brain has 2a.

    Caden has three times as many as Brain, so Caden has 3(2a)=6a.

    Daryl has five times the number of marbles as Caden, so Daryl has 5(6a)=30a.

    We are given that these 4 people together have 78 marbles.

    Angela’s + Brain’s + Caden’s + Daryl’s =78

      a          +    2a      +   6a        + 30a      =78

    Combine the like terms:

    39a=78

    Divide both sides by 39:

      a=78/39

       a=2
