Question

Quizplus · Accepted Answer

To calculate the percentage of total kcal as fat, we need to first multiply the grams of each type of fat by their respective energy density and add them up.

Saturated fat: 13g x 9 kcal/g = 117 kcal
Monounsaturated fat: 10g x 9 kcal/g = 90 kcal
Polyunsaturated fat: 27g x 9 kcal/g = 243 kcal

Total fat: 117 + 90 + 243 = 450 kcal

To find the percentage of total kcal as fat, we need to divide the total fat kcal by the total kcal of the meal and multiply by 100:

Percentage of kcal from fat = (450 kcal / 1200 kcal) x 100 = 37.5%

Therefore, the answer is C (37.5).
