Q: A meal contains 60 grams of carbohydrate, 20 grams of protein, 10 grams of fat, and 5 grams of alcohol. How many total kilocalories does this meal provide? (Use: CHO = 4 kcal/g, Pro = 4 kcal/g, Fat = 9 kcal/g, Alcohol = 7 kcal/g)

$$60 \times 4 + 20 \times 4 + 10 \times 9 + 5 \times 7 = 240 + 80 + 90 + 35 = 445$$ kcal

Q: A nutrition label states that a serving contains 8g fat, 24g carbohydrate, and 4g protein. What percent of the total calories comes from fat? (Use: CHO = 4 kcal/g, Pro = 4 kcal/g, Fat = 9 kcal/g)

$$\frac{8 \times 9}{8 \times 9 + 24 \times 4 + 4 \times 4} \times 100 = \frac{72}{72 + 96 + 16} \times 100 = \frac{72}{184} \times 100 \approx 39.1\%$$
