The Nutrition Facts panel on a granola bar says that it has 10 grams of fat, 15 grams of carbohydrate, and 5 grams of
protein per bar. Approximately how many kilocalories are in this bar?

Respuesta :

1g of fat = ~9kcal
1g of pro = ~4kcal
1g cho = ~4kcal

Therefore: 10g fat x 9= 90kcal
15g cho x 4 = 60kcal
5g pro x 4= 20kcal

90+60+20 = 170

Approximately 170kcal are in this bar.
