The calorie count of a serving of food can be computed based on its composition of​ carbohydrate, fat, and protein. The calorie count C for a serving of food can be computed using the formula Upper C equals 4 h plus 9 f plus 4 p​, where h is the number of grams of carbohydrate contained in the​ serving, f is the number of grams of fat contained in the​ serving, and p is the number of grams of protein contained in the serving. A serving of raisins contains 148 calories and 29 grams of carbohydrate. If raisins are a​ fat-free food, how much protein is provided by this serving of​ raisins?

Answer:

The raisins provide 8 grams of protein.

Step-by-step explanation:

First wrote the information as a equation:


C=4h+9f+4p

Where: C is calories, h carbohidrates, f fats and p protein

The information given for the raisin, 148 calories, 0 fat and 29 carbohidrates. That into a equation.


148=4(29)+9(0)+4p

We clear p from the equation

14
(148-4(29))/(4) =p=8 gr
