Number of red boats (r) = 9

Total number of boats = ?

As per question, three quarters are white. So,

Number of white boats (w) =

Now, boats remaining are given as:

Remaining boats = Total boats - White boats

Remaining boats =

As per question, 4/7 of the remaining boats are blue.

Number of blue boats (b) =

Now, the rest are red. So,

Number of red boats (r) = Total number - ( White boats + Blue boats )

Plug in 9 for 'r', for 'w' and for 'b'. Solve for 'x'. This gives,

Therefore, the total number of boats in the marina are 84.
