Answer:
4
Step-by-step explanation:
1. Divide total number of students by number of students per car (use remainder rather than decimal)
13/4 = 3, remainder 1
In this case, round up because no student can be left behind. 4 cars will be used.
Answer: 4
Step-by-step explanation: if you divide 4 into 13 you get 3.25. Which means you can fit 4 students (12 total) each in 3 cars. That leaves 1 student. You would need one more car.
