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)
