Final answer:
After calculating the calories from fat, carbohydrates, and protein, the total comes to 199 calories, which rounds to 200 calories. Thus, the correct option is C, 200 calories.
Step-by-step explanation:
The question is asking about the calorie content of a serving of nuts that contains 15 grams of fat, 9 grams of carbohydrate, and 7 grams of protein. To calculate the total calorie content, we use the fact that each gram of fat contains 9 calories, each gram of carbohydrates and protein contains 4 calories each.
Using this information, we calculate the total calories as follows:
- Calories from fat: 15 grams × 9 calories/gram = 135 calories
- Calories from carbohydrates: 9 grams × 4 calories/gram = 36 calories
- Calories from protein: 7 grams × 4 calories/gram = 28 calories
Adding them together gives:
135 calories + 36 calories + 28 calories = 199 calories
Since the provided options are in whole numbers, we round 199 to the nearest whole number, which is 200 calories. Therefore, the closest answer is 200 calories which corresponds to option C.
