Question

Suppose you ate an entire bag of potato chips and drank a 16-ounce cola while you studies for an exam. Together these items contain 144 grams of carbohydrate (in the cola and chips), 12 grams of protein (from the chips), 60 grams of fat (also in the chips), and 10 mg of vitamin C (amazingly enough in the chips). How many kilocalories did you consume?

Answer 1

Answer:

Total of $1164.187$ kilo-calories are consumed.

Explanation:

In order to determine the total calories present in any food item, the calories contribution of each of its constituents must be know.

Here,

Calories in one gram of carbohydrate $= 4$ kilocalories

Calories in one gram of protein $= 4$ kilocalories

Calories in one gram of fat  $= 9$ kilocalories

As per the details provided on Coca-Cola website, calories in 16-ounce cola $= 187$ calories $= 0.187$ kilocalories

Thus, total calorie in  an entire bag of potato chips and  16-ounce cola

$(144 * 4) + ( 12 * 4) + (60 * 9) + 0.187\\= 576 + 48 + 540 + 0.187\\= 1164.187$

Total of $1164.187$ kilo-calories are consumed.
