b. how many watches must the company sell in order to break even?
~~~~~~~~~~~~~~~~~~~~~~~~~~



        The solution and calculations by @MowMow in his post for part  (a)  are  INCORRECT.


        I came to bring a correct solution.



<pre>
We are given that 100,000 watches are sold.  100,000 is  1000  hundreds,
so, we should substitute 1000 for 'd' into the formula 

    P(1000) = 2*1000^2 + 13*1000 - 6 = 2012994.


So, the profit is  2012994  in tens of thousands of dollars, or  20,129,940,000  dollars.


<U>ANSWER to part (a)</U>.  The profit is 20,129,940,000 dollars.
</pre>

Solved correctly.
