A piece of cheese pizza contains 52 grams of carbohydrate, 24 grams of protein, and 30 grams of fat. How many calories will it provide? (Underline correct answer) a. 544 calories b. 574 calories c. 624 calories d. 645 calories

Answer

To find the total number of calories, we must use the standard caloric values for each macronutrient: carbohydrates provide 4 calories per gram, protein provides 4 calories per gram, and fat provides 9 calories per gram. First, calculate the calories from carbohydrates: 52 grams * 4 calories/gram = 208 calories. Second, calculate the calories from protein: 24 grams * 4 calories/gram = 96 calories. Third, calculate the calories from fat: 30 grams * 9 calories/gram = 270 calories. Finally, add all the values together: 208 + 96 + 270 = 574 calories. Therefore, the correct answer is option b (574 calories).
