Answer:

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).
