.
<pre>

    650 + 75*w < 150*w,


where w is the number of weeks.  Solve this equation


    650 < 150w - 75w

    650 < 75w

     w  < 650/75 = 8.666.


The problem wants you to find the maximum integer value of " w ", when inequality (1) is still valid.


So, you round the value of 8.666 to maximal lesser integer, which is 8.
