Recall the binomial theorem.

1. The binomial expansion of
is

Observe that


When we multiply these by
,
•
and
combine to make 
•
and
combine to make 
and the sum of these terms is

2. The binomial expansion is

We get the
term when
:

23, 46, 92, 184, 368, 736, 1472, 2944, 5888.
The company will have 5888 sales.
