<h2>Calories percentage in fat</h2>
Explanation:
- The number of calories gained when eating different types of food differs. Some food types are more fattening relative to other types.
- The number of calories consumed when eating carbohydrates - 4 calories/ gram * 250 g = 1000 calories
- Calories gained eating proteins -4 calories/gram * 75 g = 300 calories
- Calories gained eating fats- 9 calories/ gram * 60 g = 540 calories
- Total amount of calories consumed = 1000 + 300 + 540 = 1840 calories
- Percentage of calories coming from fats = 540/1840 *100% = 29.3 %
- Hence, the right answer is " 29.3% of calories of her day's intake came from fat"
