A food contains 8 grams of fat, 4 grams of carbohydrates, and 5 grams of protein. That would be equivalent to __________ calories.

To determine the total caloric content of the food, we can calculate the calories provided by each macronutrient based on their standard caloric values.

• Fat provides 9 calories per gram. Therefore, with 8 grams of fat, the caloric contribution is calculated as:

(8 \text{ grams} \times 9 \text{ calories/gram} = 72 \text{ calories}).

• Carbohydrates provide 4 calories per gram. For the 4 grams of carbohydrates, the calculation is:

(4 \text{ grams} \times 4 \text{ calories/gram} = 16 \text{ calories}).

• Protein also provides 4 calories per gram. Thus, for 5 grams of protein:

(5 \text{ grams} \times 4 \text{ calories/gram} = 20 \text{ calories}).

Now, we can sum the calories from all three macronutrients:

(72 \text{ calories (from fat)} + 16 \text{ calories (from carbohydrates)} + 20 \text{ calories (from protein)} = 108 \text{ calories}).

This total of 108 calories accurately reflects the caloric
