select the correct answer.\na roasted chicken multigrain sandwich contains 42 g protein, 7 g fat, and 34 g carbohydrates. how much energy does the sandwich provide?\na. 747 calories\nb. 542 calories\nc. 502 calories\nd. 367 calories\ne. 332 calories
Answer
Explanation:
Step1: Calculate energy from protein
Protein provides 4 calories per gram. So energy from protein = 42 g×4 calories/g = 168 calories.
Step2: Calculate energy from fat
Fat provides 9 calories per gram. So energy from fat = 7 g×9 calories/g = 63 calories.
Step3: Calculate energy from carbohydrates
Carbohydrates provide 4 calories per gram. So energy from carbohydrates = 34 g×4 calories/g = 136 calories.
Step4: Calculate total energy
Total energy = energy from protein+energy from fat+energy from carbohydrates = 168 + 63+136 = 367 calories.
Answer:
D. 367 calories
