Question

find the number of grams a protein in an 8-oz serving of vanilla yogurt that contains 179 calories ,3 grams of fat and 31 grams of carbohydrate.

Answer 1

Given:

The number of calories contain in an 8-oz serving of vanilla yogurt, C = 179 calories

Fat,f = 3 grams

Carbohydrates, c = 31 grams

The Nutrition formula C = 9f + 4p + 4c gives the number of calories C in a serving of food that contains f grams of fat, p grams of protein, and c grams of carbohydrates.

So C = 9f + 4p + 4c

179 = 9*3 + 4p + 4(31)

179 = 27 + 4p + 124

179 = 151 + 4p

4p = 179 - 151

4p = 28

p = 28/4

p = 7

Therefore the number of grams a protein in an 8-oz serving of vanilla yogurt is 7 gram
