Question

There are 4 calories in a gram of carbohydrates, 4 calories in a gram of protein, and 9 calories in a gram of fat. What is an equation that relates the number of calories, n, with the number of grams of carbohydrates, c, the number of grams of protein, p, and the number of grams of fat, f?

Answer 1

n = 4c + 4p + 9f

Explanation:

In this equation, 4c represents the number of calories from carbohydrates (4 calories per gram), 4p represents the number of calories from protein (4 calories per gram), and 9f represents the number of calories from fat (9 calories per gram). By summing up these contributions, we obtain the total number of calories (n).
