Problem 2:
Calculate the total weight of a balanced meal if it contains g of proteins, g of carbohydrates, and g of fats.
Solution:
To find the total weight, we sum the individual components: The total weight is g.
Explanation:
A balanced diet for an adolescent involves summing the mass of various macronutrients to ensure nutritional targets are met.
