Now let's try Goal Seeking

Using the same example, find out what SP is needed to achieve a
Margin of 10000 in Y1.

Since we are only interested in Y1, first tell FINAR that this is
the Column to work on.

ØP1123That's  the  end  of  this   Lesson.
Before  progressing  to   Lesson   8
(Graphics), do some experiments with
SENSITIVITY  and  FIND  using   some
    models of your own in  FINAR.
