Answer: To determine the number of school buses the teacher needs to reserve, we need to divide the total number of people (students, teachers, and parents) by the capacity of each school bus.
Let's assume the total number of people going on the trip is 'N'.
The teacher needs to reserve 1 school bus for every 44 people. Therefore, the number of school buses required can be calculated as:
Number of school buses = (Total number of people) / (Capacity of each school bus)
Number of school buses = N / 44
To find the exact number of school buses, we would need to know the total number of people going on the trip. If you provide that information, I can help you calculate the number of school buses needed.
