Answer:
His total calorie consumption for the day is:
Option C. 1.820 kcal
Step-by-step explanation:
Protein and carbohydrates both contain 4 calories per gram, while fat provides 9 calories per gram, then:
1.) 160 grams of carbohydrates contain:
160 grams * (4 cal/gram)=640 cal
2.) 100 grams of fat contain:
100 grams * (9 cal/gram)=900 cal
3.) 70 grams of protein contain:
70 grams * (4 cal/gram)=280 cal
Then, his total calorie consumption for the day is:
T=640 cal + 900 cal +280 cal
T=1,820 cal
T=1,820 cal (1 kcal / 1,000 cal)
T=1.820 kcal
