Prairie Farms® original strawberry cheesecake yogurt weighs 170 grams and contains 76% water, 20% carbohydrate, 3% protein, and 0.1% lipid. Given this information, one serving of Prairie Farms® original strawberry cheesecake yogurt is 158 kilocalories.

True

False

Answer: True

Explanation:

The first step to caculating the total number of kilocalories in one serving of the yogurt is to know how many grams are water, carbohydrates, proteins, or lipids, based on the given porcentages.

Water: 170 x 0.76 = 129.2 g

Carbohydrate: 170 x 0.20 = 34g

Protein: 170 x 0.03 = 5.1g

Lipid: 170 x 0.001 = 0.17g

The second step is to calculate their respective amount of kilocalories, considering that carbohydrates and proteins have 4 kilocalories per gram, and lipids have 9.

(129.2g x 0 kcals) + (34g x 4 kcals) + (5.1g x 4 kcals) + (0.17g x 9 kcals)

0 + 136 + 20.4 + 1.53 = 157.93 (158 round up)
