<human>:  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?
<bot>: How many buckets of fish are given to the dolphins each day? ** The dolphins are fed 4/2 = <<4/2=2>>2 buckets of fish each day.
How many buckets of fish are given to the sea animals each day? ** The sea animals are fed 4 x 5 = <<4*5=20>>20 buckets of fish each day.
How many buckets of fish are given to the sharks, dolphins, and sea animals each day? ** So, the Mystic Aquarium needs 4 + 2 + 20 = <<4+2+20=26>>26 buckets of fish each day.
How many buckets of fish are given to the sharks, dolphins, and sea animals each week? ** Thus in a week, it needs 26 x 7 = <<26*7=182>>182 buckets of fish.
How many weeks will 546 buckets of fish last? ** Therefore, 546 buckets of fish will last for 546/182 = <<546/182=3>>3 weeks.
