Justice has 3 ferns, 5 palms, and 7 succulent plants in her house. If she wants a total of 24 plants in her home, how many more plants does she need? Give me reasons, before answering the question
Justice currently has 3 + 5 + 7 = 15 plants in her house. Justice needs 24 - 15 = 9 more plants. So the final answer is 9.
