[Question]: 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?
[Answer]: 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 answer is 3.

[Question]: Olaf has an aquarium. He has fish in 3 different colors: orange, green, and blue. Blue fish make up half of all the fish in the aquarium. There are 15 fewer orange fish than blue fish. How many green fish are there when the total number of fish in the aquarium is 80?
[Answer]: If there are 80 fish in total, then there are 80 fish / 2 = 40 blue fish. The orange fish count is 15 less than blue, so it's 40 fish - 15 fish = 25 fish. Olaf has then 80 fish - 25 fish - 40 fish = 15 green fish.
So the answer is 15.

[Question]: Jose is a collector of fine wines. His private cellar currently holds 2400 bottles of imported wine and half as many bottles of domestic wine as imported wine. If Jose holds a party and the guests drink one-third of all his wine, how many bottles will remain in his cellar?
[Answer]:
Jose has half as many bottles of domestic wine as imported wine, or 2400 / 2 = 1200 bottles of domestic wine. In total, he has 2400 + 1200 = 3600 bottles of wine. If the guests drink one - third of all his wine, then they will have consumed 3600 / 3 = 1200 bottles of wine. Thus, after the party, Jose's private cellar will have 3600 - 1200 = 2400 remaining bottles of wine.
So the answer is 2400.
