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?
582 kilocalories
To calculate the total number of kilocalories (kcal) Jane ate at breakfast, you need to know the energy content of each macronutrient (carbohydrate, protein, and fat). Here are the energy values per gram for each macronutrient:
- Carbohydrate: 1 gram = 4 kilocalories (kcal)
- Protein: 1 gram = 4 kilocalories (kcal)
- Fat: 1 gram = 9 kilocalories (kcal)
Now, let's calculate the energy from each macronutrient:
Carbohydrates: 85 grams * 4 kcal/gram = 340 kcal
Protein: 20 grams * 4 kcal/gram = 80 kcal
Fat: 18 grams * 9 kcal/gram = 162 kcal
Finally, add up the energy from each macronutrient to find the total energy consumed:
Total energy = Carbohydrates + Protein + Fat
Total energy = 340 kcal + 80 kcal + 162 kcal
Total energy = 582 kcal
Therefore, Jane consumed 582 kilocalories at breakfast.
To determine the number of kilocalories Jane consumed at breakfast, we need to know the energy content of each macronutrient. Here are the energy values for each macronutrient per gram:
- Carbohydrate: 4 kilocalories per gram
- Protein: 4 kilocalories per gram
- Fat: 9 kilocalories per gram
Now, we can calculate the kilocalories from each macronutrient:
Carbohydrate: 85 grams * 4 kilocalories/gram = 340 kilocalories
Protein: 20 grams * 4 kilocalories/gram = 80 kilocalories
Fat: 18 grams * 9 kilocalories/gram = 162 kilocalories
Finally, we can add up the kilocalories from each macronutrient to find the total:
340 kilocalories + 80 kilocalories + 162 kilocalories = 582 kilocalories
Therefore, Jane consumed 582 kilocalories at breakfast.
