Question: If Lucy would give Linda $5, Lucy would have the same amount of money as Linda. If Lucy originally had $20, how much money did Linda have at the beginning?
Answer with step-by-step thinking: After giving $5, Lucy has $20 - $5 = $15 left. Since Linda has $15 after receiving $5, then she had $15 - $5 = $10 at the beginning.
So the answer is 10.


Question: Dennis collected 10 rocks. He put all of them in his aquarium but his fish ate half of them. He was able to make the fish spit two out. How many of Dennis's rocks are left?

Dennis had 10 / 2 = 5 rocks left after the fish ate them. He made the fish spit two out, which left Dennis with 5 + 2 = 7 rocks.
So the answer is 7.
