Hello there. To solve this question, we'll have to simply subtract and divide the numbers to find how many students were in each bus.
Knowing that for this field trip, 17 from 367 students went by cars, we know that 350 went by bus.
If there were 10 buses and we assume that all the buses transports the same amount of students, to find this amount, we just divide:
350/10 = 35
Therefore, 35 students were in each bus for this field trip.
