Mrs. Jackson has four boxes of Christmas decorations. There are 15 decorations in each box. She was only able to use 35 decorations and decided to give the rest to her neighbor. How many decorations did she give? Give me reasons, before answering the question
Mrs. Jackson had a total of 4 x 15 = 60 decorations. Then she gave 60 - 35 = 25 decorations to her neighbor. So the final answer is 25.
