Question

1.4.AP-6 3 Question Help 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 C = 3h + 13f + 7p, 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. Solve this formula for f, the number of grams of fat contained in a serving of food.​

Answer 1

f = (C-3h-7p)/13

Explanation:

Given the equation of calorie count of food computed by:

C = 3h + 13f + 7p

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

We are to make f the subject of the formula as shown:

C = 3h + 13f + 7p

13f = C-3h-7p

Divide through by 13

13f/13 = (C-3h-7p)/13

f = (C-3h-7p)/13

Hence the formula for f, the number of grams of fat contained in a serving of food is f = (C-3h-7p)/13
