Solution (Part-A)

Note that:

  • Given clue: A class must have fewer than 18 students

Let's reread the clue carefully.

{A class} must have {fewer} than {18 students}

↥ ↥ ↥

n < 18

The inequality formed: n < 18

This means that the solution of the inequality can be anything except 18 or above 18.

Solution (Part-B)

Note that:

  • Given clue: The class must have at least 15 students

Let's reread the clue carefully.

{The class} must have {at least} {15 students}

n ≥ 15

The inequality formed: n ≥ 15

This means that the solution of the inequality can be 15 or less than 15.

Solution (Part-C)

The value of n that can be a solution of both inequalities can be 15, 16, and 17.

Hoped this helped!

Answer:

n ≤ 18

Explanation:

The students can be 18 but they can't be greater than 18 so the inequality must be n ≤ 18.
