Answer(or question to Mentor): Second time answering question:
There were 14gfat x 9 cal/ g fat = 126 calories of fat;
36g carbohydrates x 4 cal/g carb. = 144 calories of carbs;
15 g protein x 4 cal/g protein = 60 calories of protein.
126 + 144 + 60 = 330 calories
330/2000 = 33/200 = 16.5/100 = 16.5% of the daily caories
The cheeseburger has 14g fat + 36 g Carbs + 15 g protein = 65 grams. The fat was 14/65 = .215 = 21.5 % of the total cheeseburger.
Challenge: If 3 nuggets are left after 1/2 were eaten by Miles, miles must have had 6 from Juan. Juan had eaten 3/4 of the nuggets, and left 6. 6 then was 1/4 of what he had started with, so 6 x 4 = 24, so he started with 24 from Ralph. Ralph had eaten 1/3, which left 24. 24 then is 2/3 of what he started with. 2/3 x = 24. 24 x 3 divided by 2 = 36, so there were 36 nuggets to start with.

Instructor Comments: Cam,
This is a perfect response. Tell him that you will post it in the highlighted solutions next week. Perhaps you can challenge him with the following problem: instead of having Ralph eat 1/3 of the nuggets, suppose we change the problem to say that he ate 2 nuggets. Now how many did Lani purchase?--Dr. B
