Answer:
12 vans
7 Buses
Step-by-step explanation:
I tried multiple versions but I finally got it right.
Since the buses can hold 25 students at a time I multiplied it by 7.
7 x 25 = 175
Then you'll need to find the remainder.
259-175 = 84
This number would be used to find the students going in the van
84/7= 12
So in total there would be 12 vans
and 7 buses
I hope this helps
