The problem asks us to solve the inequality $n + 18 \le 24$ and graph the solution on a number line.

1. Problem Description

The problem asks us to solve the inequality $n + 18 \le 24$ and graph the solution on a number line.

2. Solution Steps

First, we need to isolate the variable $n$ in the inequality. To do this, we subtract 18 from both sides of the inequality:

$n + 18 - 18 \le 24 - 18$

$n \le 6$

This means that $n$ can be any number less than or equal to

6.

Now, we graph the solution on a number line. We put a closed circle at 6 to indicate that 6 is included in the solution. Then we draw an arrow to the left, indicating that all numbers less than 6 are also included.

3. Final Answer

$n \le 6$
