Answer:
7 students in each van and 52 students in each bus.
Step-by-step explanation:
v = no of students in van, b = no of student in bus
High school A ⇒ 3v + 6b = 333 ---------- Equation (1)
High school B ⇒ 11v + 6b = 389 ------------ Equation (2)
Solve equation (1) & (2) simultaneously :
11v + 6b = 389
3v + 6b = 333
----------------------- MINUS
8v + 0 = 56
v = 56 / 8
v = 7
Put v = 7 into Equation (1) to get b:
3v + 6b = 333
3 (7) + 6b = 333
21 + 6b = 333
6b = 312
b = 312 / 6
b = 52
So there are 7 students in each van and 52 students in each bus.
