Question 967524
<pre>
You did make a mistake because -384+258 is -126, not -642.

However that's no help because 28 doesn't go into 126 evenly 
either.  The solution is 8.5 roses and 4.5 lilies.

But who wants half of a flower?  Not I.  The problem is
obviously botched.  Be sure to point it out to your teacher.
