Aserving of a breakfast cereal contains 8.3 g of protein, 13.8 g of carbohydrates, and 4.8 g of fat. what is the calorie content of a serving of this cereal if the average number of calories for fat is 9.1 calories/g, for carbohydrates is 4.1 calories/g, and for protein is 4.1 calories/g?

The calorie content of the serving of cereal is 134.29 Calories.

Explanation:

We are given:

Average number of calories for fat = 9.1 Cal/g

Average number of calories for carbohydrates = 4.1 Cal/g

Average number of calories for proteins = 4.1 Cal/g

Mass of fat = 4.8 g

Mass of carbohydrates = 13.8 g

Mass of protein = 8.3 g

To calculate the calorie content in all the minerals, we apply unitary method:

If 1 gram of fat has 9.1 calories.

So, 4.8 grams of fat will have =

The calorie content in given amount of fat is 43.68 Calories.

If 1 gram of carbohydrate has 4.1 calories.

So, 13.8 grams of carbohydrate will have =

The calorie content in given amount of carbohydrate is 56.58 Calories.

If 1 gram of protein has 4.1 calories.

So, 8.3 grams of protein will have =

The calorie content in given amount of protein is 34.03 Calories.

Total amount of calorie in cereal = 43.68 + 56.58 + 34.03 = 134.29 Calories

Hence, the calorie content of the serving of cereal is 134.29 Calories.

you can show her once, and if she doesn't do it, do what i do: i take away one of her privileges until she learns. it worked for my sister but note every child is different. or you canput her on 'time out' if she doesn't learn.
