Answer

602 kcal Explanation 1. Calculate carbohydrate calories Carbohydrates provide 4 kcal per gram. Multiply 85 grams by 4: 85 \times 4 = 340 kcal. 2. Calculate protein calories Proteins provide 4 kcal per gram. Multiply 25 grams by 4: 25 \times 4 = 100 kcal. 3. Calculate fat calories Fats provide 9 kcal per gram. Multiply 18 grams by 9: 18 \times 9 = 162 kcal. 4. Sum total calories Add the calories from carbohydrates, proteins, and fats: 340 + 100 + 162 = 602 kcal.
