Final answer:
Insufficient information was provided to determine the exact number of buses needed for the students and teachers. The process involves dividing the total number of people by a bus's capacity and rounding up the result.
Step-by-step explanation:
To determine how many buses are needed to hold all the students and teachers, we first need to know the total number of students and teachers and the capacity of each bus. Without specific numbers provided in the question, we cannot calculate an exact number of buses needed. The provided information is insufficient to give a precise answer to the student’s schoolwork question. However, as a tutor, I would guide the student through the process of dividing the total number of people by the seating capacity of a bus to find the number of buses required, rounding up to ensure there is space for everyone, if such data were available.
