To solve the inequality \( c + 4 < 5 \), we can isolate \( c \) by subtracting 4 from both sides:
\[ c + 4 - 4 < 5 - 4 \] \[ c < 1 \]
This means that \( c \) can take any value less than 1.
Step 1: Identify the Endpoints
The endpoint in this case is 1.
Step 2: Determine the Type of Endpoint
Since the inequality is \( c < 1 \), we will use an open endpoint at 1. This means that 1 is not included in the solution.
Step 3: Graph the Solution
To graph the solution:
- Draw a number line.
- Mark the point at 1.
- Use an open circle at 1 to indicate that it is not included in the solution.
- Shade to the left of 1 to indicate that all numbers less than 1 are included in the solution.

Summary:
- The solution to the inequality is \( c < 1 \).
- The graph features an open circle at 1, with a shaded region extending to the left, indicating all values less than 1.
