Alexandra decides to climb mt. krumpett, which is 5000 m m high. she determines that this will require a total of 3150 kcal k c a l of energy for the trip. for her food supply, she decides to take nutrition bars. the label states that each bar contains 50 g g of carbohydrates, 10 g g of fat, and 40 g g of protein. how many nutrition bars should alexandra pack?

Respuesta :

Alexandra should pack 7 nutrition bars for climbing the Mt. Krumpett that will require 3150 kcal of energy for the trip.

According to the question, one pack of nutrition bar contains

  1. carbohydrates = 50 g
  2. fats = 10 g
  3. proteins =  40 g

To calculate the energy of food (in Kcal), the formula used will be:

Energy = 4 × [carbohydrates (gm) + proteins (gm)] + 9 × [fats]

Energy (E) = 4 × [50 + 40] + 9 × [10]

E = 360 + 90

E = 450 Kcal.

One pack of nutrition bar contains 450 Kcal of energy, therefore to calculate the number of packs required, the total energy required to climb should be divided by the energy of one bar.

Number of nutrition bars = 3150 Kcal / 450 Kcal

Number of nutrition bars = 7.
