More than 450 students went on a field trip. Ten buses were filled and 5 more students traveled in a car.

Question

Write an inequality to represent the situation. Be sure to define your variable.

 Solve the inequality to find the minimum number of people on each bus

Answer 1

Let b = the number of students on each bus.

 

10b + 5 > 450

10b > 445

b = 44.5

 

You can't have half a student, and 44 students per bus does not give us 450, so 45 students minimum per bus.
