Answer:
A.- 300kcal (315kcal) / B.- 100kcal (108kcal) - arround (30-35%)
Explanation:
In order to determine how many kilocalories have the meal, you have to multiply the macro-molecule grams as the following rule:
lipids * 9 / carbohydrates * 4 / proteins * 4
then
7g*9 + 36g*4 + 27g*4 = 63kcal + 144kcal + 108kcal (P) = 315kcal
