Final answer:
To determine how many students were in each bus, subtract the 8 students who drove in cars from the total of 558, then divide by the number of buses (10). The calculation shows that there were 55 students per bus.
Step-by-step explanation:
The question asks us to find out how many students were in each bus on a field trip. First, we need to calculate the total number of students who went on the buses by subtracting the students who drove in cars from the total number of students who went on the trip. The calculation is as follows: 558 total students - 8 students in cars = 550 students on buses.
Now that we know the number of students who were on buses, we divide this number by the number of buses to find out the number of students per bus. There were 10 buses, so we divide 550 students by 10 buses, which equals 55 students per bus. Therefore, the correct answer is B) 55 students.
