1. **State the problem:** Tanvi bought 12 rolls of toilet paper for 15. We need to find the price per roll.
2. **Formula:** Price per roll = \frac{\text{Total cost}}{\text{Number of rolls}}
3. **Substitute values:**
$$\text{Price per roll} = \frac{15}{12}$$
4. **Simplify the fraction:**
$$\frac{15}{12} = \frac{\cancel{15}}{\cancel{12}} = \frac{5}{4}$$
5. **Convert to decimal:**
$$\frac{5}{4} = 1.25$$
6. **Answer:** The price per roll is **1.25**.
This matches the option "$1.25 per roll".
