John has 20% more boxes than Jules. Jules has 5 more boxes than Joseph. Joseph has 80% fewer boxes than Stan. If Stan has 100 boxes, how many boxes does John have? Give me reasons, before answering the question
Joseph has 100 * 0.80 = 80 less boxes than Stan. Joseph has a total of 100 - 80 = 20 boxes. Jules has 20 + 5 = 25 boxes. John has 25 * 0.20 = 5 more boxes than Jules. John has a total of 25 + 5 = 30 boxes. So the final answer is 30.
