<u>Sketch A</u>
In sketch A, we have the following observations:
- <em>The arrow faces left (this implies less than)</em>
- <em>The dots on -2 and -5 are closed dots (this implies less than or equal to).</em>
<em />
Hence, the inequality is:

<u>Sketch B</u>
In sketch B, we have the following observations:
- <em>The arrow faces right (this implies greater than)</em>
- <em>The dots on -4 and 3 are closed dots (this implies greater than or equal to).</em>

After six and half hours for studio A and after eight hours for studio B, the total costs of both studios will be the same.
<h3>
What is Rate ?</h3>
Rate is a measure or quantity measured against another quantity or measure which is the ratio between two related quantities in different units
It is given that you want to create a piece of pottery at an art studio. The total cost is the cost of the piece plus an hourly studio fee. The costs at two studios are shown.
- Studio B: $6.50 per hour.
Multiply both together. That is,
8 x 6.5 = $52
The two cost will be the same at $52. By that time,
Studio A will be six and half hours.
Studio B will be eight hours.
Therefore, after six and half hours for studio A and after eight hours for studio B, the total costs of both studios will be the same.
