Elio makes candles that are $14\text{ cm}$ tall. Each candle burns $8$ hours before going out. He is wondering how many hours a $21\text{ cm}$ tall candle can burn for.
He assumes that the relationship between the height of a candle and number of hours it burns $(h)$ is proportional.
**Which proportion could Elio use to model this situation?**

**Solve the proportion to determine how long a $21 \text{ cm}$ tall candle can burn for.**
