Final answer:
Becky must have 24 DVDs to watch a different one every evening for 24 consecutive evenings.
Step-by-step explanation:
The question asks how many DVDs Becky must have if she wants to watch one each evening for 24 consecutive evenings. To answer this question, assume that Becky watches a different DVD each evening. Thus, the logical conclusion is that Becky must have at least as many DVDs as the number of evenings she plans to watch them. Therefore, the answer is c) 24 DVDs.
