My post-solution note.
In my view, the problem formulation is not so accurate as it should be.
From the text, I can not understand, if the baskets for coffee and tea are separate or not.
My solution and my answer are for the case when EACH basket contain both coffee and tea.
If you meant separate baskets, then the answer is 8 + 8 = 16.
I just used to think, that persons who compose the problem for this forum,
are not able IN PRINCIPLE to do it accurately.
