Annette [7]

Answer:

Carbohydrate = 57.023g

Fats = 20.736g

Proteins = 25.919g

Explanation:

According to this question, Valerie is planning to eat at dinner meal that has a total of 800 Calories.

- 55% calories come from carbohydrate i.e. 55/100 × 800 = 440 calories

- 20% calories come from fat i.e. 20/100 × 800 = 160 calories

- 25% calories come from proteins i.e. 25/100 × 800 = 200 calories

Since 7.716 calories = 1g

1. Amount of carbohydrates in gram = 440/7.716 = 57.023g

2. Amount of fats in gram = 160/7.716 = 20.736g

3. Amount of proteins in gram = 200/7.716 = 25.919g
