Question

a food label says one serving contains 300 calories, 20g of total fat, and 8g of carbohydrates. how many grams of protein does one serving c
a. 13g
b. 22g
c. 32g
d. 44g
e. 88g

Explanation:

Step1: Calculate calories from fat

Fat provides 9 calories per gram. So, calories from fat = \(20 \times 9 = 180\) calories.

Step2: Calculate calories from carbohydrates

Carbohydrates provide 4 calories per gram. So, calories from carbs = \(8 \times 4 = 32\) calories.

Step3: Calculate calories from protein

Total calories = 300. Calories from fat + carbs = \(180 + 32 = 212\). So, calories from protein = \(300 - 212 = 88\) calories.

Step4: Calculate grams of protein

Protein provides 4 calories per gram. So, grams of protein = \(\frac{88}{4} = 22\) grams.

Answer:

b. 22g
