Answer 1

C) 42%; 11%

Step-by-step explanation:

The total calories in one Planters NUT-rition Cranberry Almond Peanut bar =

• fats: 35 grams x 23% x 9 calories = 72.45 calories
• carbohydrates: 35 grams x 57% x 4 calories = 79.8 calories
• proteins: 35 grams x 14% x 4 calories = 19.6 calories
• total 171.85 calories

percent calories from fat = 72.45 calories / 171.85 calories = 0.4216 x 100 = 42.16% ≈ 42%

percent calories from protein = 19.6 calories / 171.85 calories = 0.1141 x 100 = 11.41% ≈ 11%
