Jonah decided to set up an aquarium. He started with 14 small fish. He added 2 more, but they ate 6 of his original fish before he could remove them and take them back to the store. He exchanged them for 3 new fish. How many fish does Jonah have now? Let's think first. Chain of thought:
Jonah started with 14 fish + 2 more = 16 fish. Of the 16 fish – 6 were eaten – 2 were returned to the store = 8 fish. After he returned the fish to the store, he exchanged them for 3 new fish + 8 fish that were left = 11 fish now in his tank.
Therefore, the answer is 11.
