Haleigh Khan · Answer 1

582kilocalories

Explanation:

In 1 gram of fat, we have 9kilocalories of energy contribution

In 1 gram of carbohydrate, we have 4kilocalories of energy contribution

In 1 gram of protein, we have 4kilocalories of energy contribution.

85grams of carbohydrate was consumed, hence the total energy contribution is 85 * 4 = 340kilocalories of energy

20grams of protein was consumed, hence the total energy contribution is 20 * 4 = 80kilocalories of energy

18grams of fats was consumed, hence the total energy contribution is 18 * 9 = 162kilocalories of energy

Hence, the total kilocalories she ate at breakfast = 340 + 80 + 162 = 582kilocories
