Answer:
f = 180 - (p + c)
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)
