At the Mystic Aquarium, sharks are fed four buckets of fish each day. The dolphins are fed half as many buckets as the sharks while the other sea animals are fed five times as many buckets as the sharks. How many weeks will 546 buckets of fish last? Give me reasons, before answering the question

The dolphins are fed 4 / 2 = 2 buckets of fish each day. The sea animals are fed 4 x 5 = 20 buckets of fish each day. So, the Mystic Aquarium needs 4 + 2 + 20 = 26 buckets of fish each day. Thus in a week, it needs 26 x 7 = 182 buckets of fish. Therefore, 546 buckets of fish will last for 546 / 182 = 3 weeks. So the final answer is 3.
