If the 180 food calories found in a granola bar come entirely from p grams of protein, f grams of fat, and c grams of carbohydrate, which expresses f in terms of p and c?

f = 180 - (p + c)

Step-by-step explanation:

Food calories found in a granola bar = 180

This food calorie comes from p grams of protein, f grams of fat and c grams of carbohydrate.

So Total food calories = calories from protein + calories from fat + calories from carbohydrates.

p + f + c = 180

f = 180 - (p + c)

Therefore, the expression represents f = 180 - (p + c)

f = 180 - p - c

to find the amount of fat subtract the protein and carbs from the original 180 calories
