Answer:
Van can carry 15 and bus 51 students
Explanation:
Let's mark the number of vans with x and number of buses with y.
That allows us to write equations:
1) 11x + 9y = 624 (high school A)
2) 5x + y = 126 (high school B)
This means that we have a system of the equations with two unknowns.
We can use x or y to solve this. Let's use x, but first we need to express y through x. We said that:
5x + y = 126
That means that:
y = 126 - 5x
Now, let's plug this in the equation 1):
11x + 9(126 -5x) = 624
11x + 1134 - 45x = 624
-34x = -510
34x = 510
x = 15
So, if x is 15, let's plug it in any of the two equations:
5x + y = 126
75 + y = 126
y = 51
So, a van carry 15 and a bus 51 students.
