Susie can buy apples from two stores: a supermarket that sells apples only in bundles of 4, and a convenience store that sells single, unbundled apples. If Susie wants to ensure that the total number of apples she buys is a multiple of 5, what is the minimum number of apples she must buy from the convenience store?
Answer is 0. I checked 1.
Question is aking that Susie "must" buy apples. If answer is 0 that means she is not buying apples at all.

Any help is highly appreciated

The question doesn't say "Susie must buy apples" - it asks "what is the minimum she must buy?"

Zero is a possible answer to that question. As I responded to another poster recently about this question: what is the minimum that you must pay me to answer your question? Zero. :)
