4. Your roommate brings home a bag of cookies, and before you know it, youve eaten the whole bag. You console yourself with the fact they were fat-free cookies. The serving size is two cookies and there were 22 cookies total.

a) If each serving has 120 calories and 0.0 g of fat, how many calories have you just consumed?

b) If the full-fat version of the cookies has 120 calories and 8.0 g of fat per serving, how many grams of fat did you save by eating the fat-free cookies?

c) Now suppose your fat-free cookies actually have 0.48 g of fat per serving (legally defined as fat-free). How much fat have you actually consumed?
