40 students are traveling to the math competition in the next town. These are two vans which can carry 15 students each. which inequality will determine how many cars are needed that can carry 3 students each?

Answer 1

Let x be the number of cars needed that can carry 3 students each.

The total number of students is 40.

So, the inequality will be:

3x ≥ 40

Therefore, the equation that will determine the number of cars needed that can carry 3 students each is:
x ≥ 40 / 3, which simplifies to:
x ≥ 13.33

Since the number of cars needed must be a whole number, 14 cars will be required to transport 40 students.
