1. **State the problem:** Mr. Jackson is filling his hot tub at a rate of 11.78 liters per minute. We need to find out how much water is in the hot tub after 8 full minutes. 2. **Formula used:** The amount of water filled is given by the formula: $$\text{Total water} = \text{rate} \times \text{time}$$ where rate is in liters per minute and time is in minutes. 3. **Substitute the values:** $$\text{Total water} = 11.78 \times 8$$ 4. **Calculate:** $$11.78 \times 8 = 94.24$$ 5. **Answer:** After 8 full minutes, the hot tub contains **94.24 liters** of water.
