The problem is to solve the inequality $t + 17 \le 18$ and graph the solution on a number line.

1. Problem Description

The problem is to solve the inequality $t + 17 \le 18$ and graph the solution on a number line.

2. Solution Steps

First, we need to isolate the variable $t$ by subtracting 17 from both sides of the inequality:

$t + 17 \le 18$

$t + 17 - 17 \le 18 - 17$

$t \le 1$

The solution is $t \le 1$. This means that $t$ can be any value less than or equal to

1. On the number line, we need to plot a closed circle at 1 and an arrow extending to the left, indicating that all values less than 1 are also solutions.

3. Final Answer

The solution to the inequality is $t \le 1$. The graph on the number line has a closed circle at 1 and an arrow pointing to the left.
