I have a question. I got this right, but I still think I'm missing something. If you considered this in a Venn-diagram format, it would be clear that there can be buyer who purchase cake mix and bread mix or muffin mix and bread mix. This would alter the equation somewhat. And I noticed that you didn't consider this. Can you please explain why?

I'm not sure that I understand what you mean.

Why does the question mention bread mixes? What's the purpose of that if it isn't used to solve the problem?

I got confused too, the "bread mix" is not necessary to be mentioned (could be cookies, or pasty, you name it), it's just confuses. What it really is, is a 2x2 matrix as shown in the picture.
