Question

A serving of raisins contains 134 calories and 27 grams of carbohydrate. If raisins are a fat-free food, how much protein is provided by this serving of raisins?

Answer 1

The correct answer is 6.5 grams

To get to 134 total calories, use the 4-9-4 rule:
0 fat x 9 calories = 0 calories
27 carb x 4 calories = 108 calorie
? protein x 4 calories = 26 calories (134-108)

So 26 calories ÷ 4 = 6.5 grams protein
