Answer:
A van can carry 18 students; a bus can carry 41 students.
Explanation:
Let v = capacity of van.
Let b = capacity of bus.
School A:
3v + 12b = 546
School B:
13v + 6b = 480
Our system of equation is:
3v + 12b = 546
13v + 6b = 480
3v + 12b = 546
+ -26v - 12b = -960
-----------------------------
-23v = -414
v = 18
3v + 12b = 546
3(18) + 12b = 546
54 + 12b = 546
12b = 492
b = 41
Answer: A van can carry 18 students; a bus can carry 41 students.
