Question

Quizplus · Accepted Answer

1 gram of protein provides 4 calories. Therefore, 95 grams of protein provide 95 x 4 = 380 calories. 
To find the percentage of calories derived from protein, we divide the calories from protein (380) by the total calories (2,400) and then multiply by 100. 
[(380/2400) x 100] = 0.1583 x 100 = 15.83

Rounding to the nearest whole number, the answer is 15%, hence the answer is (C) 15.
