You need at least $\$8$ to buy a birthday cake. Let $c$ represent the cost of the cake. The steps for graphing this situation as an inequality are given below. Find the first error, if any.

The correct option is B Step 3: The solution of $c\ge 8$ is $8$ and all the numbers to the left of $8$ on the number line.
The correct steps for graphing the inequality is as given below.

Step 1: The phrase “at least” represents the symbol $\ge$. So, $c\ge 8$.

Step 2: $8$ is chosen as the starting point on the number line.

Step 3: The solution of $c\ge 8$ is $8$ and all the numbers to the right of $8$ on the number line.

Step 4: A ray starting at $8$ is drawn. It has a closed circle at $8$ and a pointing arrow towards the right of $8$.

We can represent the number line as shown below.
