<PRE><B>Question 288214</B>
&lt;b&gt;Website A:&lt;/b&gt; $127 set up fee plus $0.45/sticker(S) 
C = 127 + 0.45(S)&lt;br&gt;
&lt;b&gt;Website B:&lt;/b&gt; $100 set up fee plus $0.60/sticker(S) 
C = 100 + 0.60(S)&lt;br&gt;
To locate the crossover point, where A is less than B, we need to calculate where:
Website A &lt; Website B, so: &lt;br&gt;
127 + 0.45(S) = 100 + 0.60(S) Now subtract 100 from each side, giving:
27 + 0.45(S) = 0.60(S)&lt;br&gt; subtract 0.45(S) from each side:
27 = 0.15(S) Divide each side by 0.15, giving:
180 = S &lt;br&gt;

Now replace (S) with &lt;i&gt;any&lt;/i&gt; number from 1 to 179 in each of:
127 + 0.45(S) = Total and 
100 + 0.60(S) = Total to verify that B is indeed lower than A, 
then, while you have calculator in hand, replace (S) with any number greater than 180 and bob&#39;s your uncle!
