Kingsley's teacher instructed her to find four friends to help her carry some chairs to the school hall to be used for an upcoming event. If each student carried 5 chairs per trip and made 10 trips in total, what's the total number of chairs taken to the hall? Let's think first. Chain of thought:
Kingsley and her four friends sum up to 4 + 1 = 5 students carrying chairs. The number of chairs carried by each student after all the trips is 10 * 5 = 50. Since each student carried 50 chairs, the total number in the hall is 50 * 5 = 250.
Therefore, the answer is 250.
