Jane consumed a breakfast that contained 85 grams of carbohydrate, 20 grams of protein, and 18 grams of fat. how many kilocalories did jane eat at breakfast? jane consumed a breakfast that contained 85 grams of carbohydrate, 20 grams of protein, and 18 grams of fat. how many kilocalories did jane eat at breakfast? 123 kilocalories 1,007 kilocalories 582 kilocalories 152 kilocalories

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
