Question

1. Your roommate brings home a bag of cookies, and before you know it, you’ve eaten the whole package. You console yourself with the fact that the cookies were fat free. According to the nutrition information on the package, the serving size is two cookies (and the package contained 22 cookies).

a. If each serving has 120 Calories and 0 g of fat, how many Calories have you consumed?

b. If a serving of the full-fat version of the cookies has 120 Calories and 8 g of fat, how many Calories have you saved by eating the fat-free cookies? c. Suppose that the fat-free cookies actually have 0.48 g of fat per serving (this is still legally defined as “fat free”). How much fat have you actually consumed by eating the package of fat-free cookies?

4.The Deepwater Horizon oil spill released approximately 35,000 barrels of oil per day into the Gulf of Mexico. A barrel of oil is defined as 42 gal. How many gallons of oil were released per day?  

Explanation / Answer

1. a. Total cookies = 22

Serving size = 2 cookies

Calories per serving = 120 cal

Total calories = 120 x no. of servings = 120 x 22/2 = 1320 cal

1.b. Tatal calories = 1320

Total fat = 8 x 22/2 = 88 g

Calories consumed per gram fat = 9 cal per gram

Total calories consumed = 88 x 9 = 792 cal

Calories saved by eating fat free cokies = total calories - total calories consumed = 1320 - 792 = 528 cal

1.c. Fat per serving in fat free cookies = 0.48 g

Tatal fat = fat per serving x total servings = 0.48 x 11 = 5.28 g

2. Temp. in degC = 175 degC

Temp in deg F = (temp in deg C x 9/5) + 32

= (175 x 9/5) +32 = 347 deg F
