do not use the total expenses line EVER in these calculations
The company has been investing (thanks to shareholders who have invested their cash) in research and development, one time clinical trials., marketing campaigns, printing of materials for three new retailers etc during Q3 2015 which wasnt the same in Q3 2014
Just focus on the increase in sales of $268k (representing a 120% increase I believe)
The sales generated gross profits of $319,814 which was reinvested back into the company to develop the market place and product line.
standard BUSINESS PRACTICE
each item sold including the "free" try and tell program generates gross profits.
