Answer:
7 buses and 12 vans
Step-by-step explanation:
This is the answer because:
1) Since there are 25 students in a bus, we multiply 7 and 25:
7 x 25 = 175
2) Then, we multiply 12 and 7 together since there are 7 students in each van:
12 x 7 = 84
3) Finally, to check our answer, we just have to add 175 and 84 together to know if this is correct or not:
175 + 84 = 259
Therefore, the answer is 7 buses and 12 vans.
Hope this helps! :D
