Glad you are in this company not sure that you would have paid 70 cents I think you might have meant to type 7 cents??
I'll try my best to answer your questions from the figures in the annual report accounts..

Although the annual report does not show the separate values for SUS compared to Devise sales, however I note that most of the sales dollars from now and going forward will be weighted towards the SUS ( single use sensors)

Although not 100% accurate but it may be an indication if my interpretation of the accounts is correct then the companies mark up's and margins on sales would be as follows...

The annual report it states that the Cost of product sales for 2021 was $732,603 verses Cash from Customers $1,242,595
so $732,603 X 1.6961369 = $1,242,595 ( so the cost prices is marked up by almost 70% ( 1.696) to arrive at that sale price.

The Margin on sales is $1,242,595 - $732,603 = $509,992 and $509,992 is 41% of $1,242,595. (so the Margin is 41%)

Therefore
Mark up on goods purchased is a fraction under 70% and....
Margin on sales = 41%.

I am not an accountant, so If anybody would like to check that I have used the data from the annual report in the correct way and if needed feel free to tweek my numbers and let us know that would be appreciated.
Kind regards from fp
