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?

The answer to this question seems a little too obvious. However, I'm going to give this question a try. The question is asking you to find the minimum number of apples Susie must buy from the convenience store. Well, if the supermarket sells apples only in bundles of 4 and the total number of apples that Susie buys must be a multiple of 5, then she can buy 5 bundles of apples or a total of 20 apples in the supermarket and not have to buy any in the convenience store. The answer is A.
