~~~~~~~~~~~~~~~~~~

Let t be the number of televisions under the problem's question.

According to the problem, we can write

    at Walter's  TV store the salary is  16000 + 15*t;

    at Kristen's TV store the salary is  10400 + 35*t.


The salaries are equal when

    16000 + 15*t = 10400 + 35*t.


Simplify this equation and find t from it

    16000 - 10400 = 35t - 15t

         5600     =    20t

            t     =   5600/20 = 280.


ANSWER.  The salaries are the same when 280 televisions are sold.
