John and his wife are celebrating their first wedding anniversary. Their dinner consists of 55 grams of carbohydrates, 36 grams of protein, 27 grams of fat, and 18 grams of alcohol. What is the total caloric value of their meal

733 kcal

Explanation:

According to a system used to calculate the available energy of foods, we have the following data:

protein has 4 kcal/gcarbohydrates has 4 kcal/gfat has 9 kcal/g alcohol has 7 kcal/g

So, we are told Jhon and his wife's dinner has:

55 g of carbohydrates36 g of protein27 g of fat18 g of

Now we have to multiply these values by the kilocalories:

(55 g of carbohydrates)(4 kcal/g)=220 kcal  (36 g of protein)(4 kcal/g)=144 kcal(27 g of fat)(9 kcal/g)=243 kcal(18 g of alcohol)(7 kcal/g)=126 kcal

Then we have to sum all, giving the following result:

733 kcal

Hope the image of the frequency formula
