The output must be a simple list of lines.\nExample 1:\nInput: Gym subscription twenty five dollars and a coffee for 5 dollars\nOutput:\n\"expense\": \"Gym Subscription 25$\"\n\"expense\": \"Coffee 5$\"\nExample 2:\nInput: Groceries 150$; gas for the car sixty dollars\nOutput:\n\"expense\": \"Groceries 150$\"\n\"expense\": \"Gas For The Car 60$\"\nExample 3 (Single Item):\nInput: monthly software license 15\nOutput:\n\"expense\": \"Monthly Software License 15$\""
