Please see the attached file for full problem description. --- A popular brand of low-fat shredded cheddar cheese advertises that it provides 1.5 g of fat with 15 Calories from total fat per serving. There are 50 Calories per serving and of the total fat, 1.0 g is saturated fat. A serving is defined as ¼ cup or 28 g. Is this “low-fat” cheese? Defend your decision with some calculations. Remember that the dietary recommendation is that no more than 30 % of Calories should come from fat. 15. Fructose, C6H12O6, is a carbohydrate. a.
