Answer: 4 buses & 6 vans
Step-by-step explanation:
You have 4 buses so you would multiply 4 by 55 because each bus holds 55 students. Since you have 4 buses, you would have 6 vans because there is a total of 10 vehicles. Therefore, you would also multiply 6 by 11 because each van holds 11 students.
286 (students) = (6 x 11) + (4 x 55)
286 = 66 + 220
