<pre>
The compounding period is not given, so I will assume that compounding is made annually.


Let A be the starting amount (= principal).


Write the formula for the future value of the annually compounded account

    FV = {{{A*(1+0.14)^11}}},

or

    550000 = {{{A*1.14^11}}}.


It gives for the principal

    A = {{{550000/1.14^11}}} = 130139.56.


<U>ANSWER</U>.  The investor should invest about $130,139.56.

Solved.
