Answer
The total kilocalories for the complete meal is equal to 920 kcal.
Work Step by Step
As we have calculated in 3.62a, these are the values of energy for each type of food:
Carbohydrate: $500kcal$
Fat: $340 kcal$
Protein: $80 kcal$
We just have to sum these values to get the total energy of that meal.
$500 kcal + 340 kcal + 80 kcal = 920 kcal$
