Question

Quizplus · Accepted Answer

To determine what percentage of Shannon's kcal came from fat, we need to know the total number of kcal she consumed. We know that 1 gram of carbohydrate provides 4 kcal, 1 gram of protein provides 4 kcal, and 1 gram of fat provides 9 kcal. Therefore, Shannon consumed:

Carbohydrate: 250g x 4 kcal/g = 1000 kcal
Protein: 75g x 4 kcal/g = 300 kcal
Fat: 60g x 9 kcal/g = 540 kcal

Total kcal consumed: 1000 kcal (carbohydrate) + 300 kcal (protein) + 540 kcal (fat) = 1840 kcal

To determine what percentage of her kcal came from fat, we divide the number of kcal from fat by the total kcal and multiply by 100:

(540 kcal / 1840 kcal) x 100 = 29.3%

Therefore, approximately 29% of Shannon's kcal came from fat, making choice C the correct answer.

Yesterday Shannon Consumed 250 Grams of Carbohydrate, 75 Grams of Protein
