<PRE><B>Question 1186496</B>
.


I will assume that &amp;nbsp;&quot; n &quot; &amp;nbsp;and &amp;nbsp;&quot; N &quot; &amp;nbsp;in your post represent the same conception.



Substitute &amp;nbsp;n = 1500 &amp;nbsp;and calculate  &amp;nbsp;c = 8000 + 9*1500.



Happy calculations &amp;nbsp;(&amp;nbsp;!&amp;nbsp;)
