Answer: 367 calories.
Explanation:
Carbohydrates and proteins provide 4 calories energy per gram of carbohydrate or protein.
Fats provide 9 calories energy per gram of fat.
So, 34 grams of carbohydrate will provide 34 x 4= 136 calories.
42 grams of protein will provide 42 x 4 = 168 calories.
7 grams of fat will provide 7 x 9 = 63 calories
Total energy will be 136+ 168+ 63 = 367 calories of energy.
The sandwich will provide 367 calories of energy.
