Answer:
8 students in each van, 22 students in each bus
Explanation:
Let's say v is number of students in each van
and b the number of students in each bus.
Let's make the equations:
8v + 8b = 240
4v + 1b = 54
8v + 8b = 240
v + b = 30
b = 30 - v
now let's use b = 30 - v and insert it into 4v + 1b = 54
4v + (30 - v) = 54
3v + 30 = 54
3v = 24
v = 8
b = 30 - v = 30 - 8 = 22
