King T'Challa consumes 80 grams carbohydrate, 20 grams protein, and 10 grams fat. How many kilocalories did he eat?

Explanation:
Energy from food is calculated using standard Atwater factors: carbohydrates 4 kcal per gram, protein 4 kcal per gram, and fat 9 kcal per gram. Multiply and add: 80 g carbs × 4 = 320 kcal; 20 g protein × 4 = 80 kcal; 10 g fat × 9 = 90 kcal. Sum these: 320 + 80 + 90 = 490 kcal. So the total energy consumed is 490 kilocalories. The other totals would require different amounts of each macronutrient or different energy-per-gram values, so with these amounts 490 kcal is the correct total.
