Answer:

8 students in each van ~ 22 in each bus

Step-by-step explanation:

- Equations:

8v + 8b = 240

4v + b = 54

------

- Modify:

8v + 8b = 240

8v + 2b = 108

------

- Subtract and solve for "b":

6b = 132

b = 22 (# of students in each bus)

-----

- Solve for "v":

4v + b = 54

4v + 22 = 54

4v = 32

v = 8 (# of students in each van)
