A roasted chicken multigrain sandwich contains 42 g protein, 7 g fat, and 34 g carbohydrates. How much energy does the sandwich
Andrei [34K]

1 -

Calories per gram of:

Fat = 9

Charbohydrates ≈ 4

Proteins ≈ 4

So, now we do the math:

34g of charbohydrates equals 34*4g of calories, therefore, 136.

7g of fat equals 7*9g of calories, therefore, 63.

42g of protein equals 42*4g of calories, therefore, 168

136 + 168 + 63 = 367 grams

Answer:

367 grams of calories in the chicken multigrain sandwhich.

Just with the salmon fillet, he has already eaten enough vitamin B12, more than 100% of the recommended daily allowance. The amount of vitamin E of the salmon fillet was low, and the amount of vitamin C was null.

The boiled green beans gave him quite a lot of the vitamin C he needs, but not enough. The vitamin E that the boiled green beens provided was also not enough. The amount of vitamin B12 was null.

The sliced strawberries where enough to back up the lack of vitamin C of the boiled green beans, but not enough to back up the lack of vitamin E. The amount of vitamin B12 was null.

Math:

If we do the math needed, we see that Robert only had enough vitamin B12 and C, and that he needed way more vitamin E.

Answer:

B. - Vitamin B12 and C only.

Hope it helped,
