    Answer:

    105 boats

    Step-by-step explanation:

    Let x be the total number of boats in the marina.

    If Two-thirds of the boats in the marina are white.

    Fraction of the remaining boat= 1-⅔ =⅓

    4/7 of the remaining boats are blue.

    4/7 of ⅓ are blue

    4/7 X ⅓ = 4/21 are blue

    Fraction of Red Boats =

    1-(Proportion of white Boats +Proportion of Blue Boats)

    = 1-(2/3+4/21)=1/7

    If there are 15 red boats,

    1/7 of the total boats =15

    1/7 X x=15

    x=15X7

    x=105

    There are 105 boats in total on the marina
