1. The problem asks to express the given conditions as inequalities involving pixels per inch (ppi) and width in pixels. 2. The first condition states: 72 pixels per inch is less than or equal to the resolution, which is less than or equal to 300 pixels per inch. This can be written as: $$72 \leq \text{resolution (ppi)} \leq 300$$ 3. The second condition states: 45 pixels is less than or equal to the width, which is less than or equal to 57 pixels. This can be written as: $$45 \leq \text{width (pixels)} \leq 57$$ 4. Combining both inequalities, we have: $$72 \leq \text{resolution (ppi)} \leq 300 \quad \text{and} \quad 45 \leq \text{width (pixels)} \leq 57$$ This expresses the given information using inequalities involving pixels per inch and width in pixels.
