1. **State the problem:** We need to find the unit price per pen when a pack of 6 pens costs 4.50.
2. **Formula used:** Unit price per pen = Total cost ÷ Number of pens
3. **Apply the formula:**
$$\text{Unit price} = \frac{4.50}{6}$$
4. **Simplify the fraction:**
$$\frac{4.50}{6} = \frac{\cancel{4.50}}{\cancel{6}} = 0.75$$
5. **Interpretation:** Each pen costs 0.75.
**Final answer:** The unit price per pen is 0.75.
