1. **State the problem:** Carl ate an apple with a mass of 184 grams and peanuts with a mass of 196 grams. We need to find the total mass of Carl's snack. 2. **Formula used:** To find the total mass, we add the masses of the individual items: $$\text{Total mass} = \text{mass of apple} + \text{mass of peanuts}$$ 3. **Substitute the values:** $$\text{Total mass} = 184 + 196$$ 4. **Calculate the sum:** $$184 + 196 = 380$$ 5. **Answer:** The total mass of Carl's snack is **380 grams**.
