Answer:

Step-by-step explanation:

The given relations can be written as two equations in two unknowns. These can be solved by any of the ususal methods.

__

Let v and b represent the numbers of vans and buses used, respectively.

v + b = 24 . . . . . 24 vehicles were taken

8v +43b = 752 . . . . 752 students were transported

__

Perhaps the easiest solution is that afforded by a graphing calculator. It shows the solution to be ...

v = 8 . . . . vans required

b = 16 . . . . buses required

__

You can eliminate the v variable by subtracting 8 times the first equation from the second.

(8v +43b) -8(v +b) = (752) -8(24)

35b = 560 . . . . . simplify

b = 16 . . . . . . divide by 35

v = 24 -16 = 8 . . . . . find v from the first equation

They had to take 8 vans and 16 buses.
