Question

You buy a protein bar. The protein bar has 8grams of fat, 7grams of protein and 15 grams of carbohydrates. What is the total calorie content in this candy bar?

Answer 1

160 calories.

Step-by-step explanation:

The total calorie content in this candy bar is 160. We know that one gram of protein contains 4 calories so by multiplying it with 7 we get 28 calories from protein, one gram of fat has 9 calories so by multiplying it with 8 we get 72 calories from fats and one gram of carbohydrate contains 4 calories so by multiplying it with 15 we get 60 calories so by adding the calories of protein, fats and carbohydrates we get 160 calories in the protein bar.
