nika2105 [10]

Answer: 733 kcal

Explanation:

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

  • protein has 4 kcal/g
  • carbohydrates has 4 kcal/g
  • fat has 9 kcal/g
  • alcohol has 7 kcal/g

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

  • 55 g of carbohydrates
  • 36 g of protein
  • 27 g of fat
  • 18 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:

<h2>733 kcal</h2>
