Answer
Carbohydrate : $680kcal$
Fat: $590 kcal$
Protein: $240 kcal$
Work Step by Step
Carbohydrate:
According to the table 3.7 (Page 71), each g of carbohydrate gives 4 kcal.
Calculate the total mass of carbohydrates: $46g + 47g + 76 g = 169 g ( Carbohydrate)$
Find the total energy: $169 g \times \frac{4kcal}{1g} = 676kcal$
Don't forget to round off the numbers to the tens place: $680 kcal.$
------------
Fat:
According to the table 3.7 (Page 71), each $g$ of fat gives 9 kcal.
Calculate the total mass of fat: $40.g + 16g + 10. g = 66 g (Fat)$
Find the total energy: $66 g \times \frac{9kcal}{1g} = 594kcal$
Don't forget to round off the numbers to the tens place: $590 kcal.$
-------------
Protein:
According to the table 3.7 (Page 71), each $g$ of protein gives 4 kcal.
Calculate the total mass of protein: $47g + 4g + 10. g = 61 g (Protein)$
Find the total energy: $61 g \times \frac{4kcal}{1g} = 244kcal$
Don't forget to round off the numbers to the tens place: $240 kcal.$
