1. **State the problem:** We need to find the average score of Alice, Chris, Dan, and Emeril from their golf scores. 2. **List the scores:** - Alice: $-11$ - Chris: $2$ - Dan: $4$ - Emeril: $5$ 3. **Formula for average:** $$\text{Average} = \frac{\text{Sum of scores}}{\text{Number of scores}}$$ 4. **Calculate the sum:** $$-11 + 2 + 4 + 5 = (-11 + 2) + 4 + 5 = -9 + 4 + 5 = (-9 + 4) + 5 = -5 + 5 = 0$$ 5. **Calculate the average:** $$\text{Average} = \frac{0}{4}$$ 6. **Simplify the fraction:** $$\frac{\cancel{0}}{4} = 0$$ 7. **Final answer:** The average score of Alice, Chris, Dan, and Emeril is **0**.
