Answer to A: 1 foot
I got this answer because, since the pole goes into the ground ¼ of a foot, you add that with the amount of water there was= ¾ and you get 4/4 witch is equal to 1 foot
Megan Latham
Answer to B: 4 ¼ feet
The last time there was a storm serge, 5 feet of the pole was left, so if you subtracted 5 feet from ¾ you will get 4 ¼
Megan Latham
Answer to challenge: Yes
This is because with only 60% of the pole at the top it is not enough to keep the water out. Andy’s house only had about 10% of the pole buried. Although if there was a strong flood the stilts would still be standing but the house would be gone.

Instructor Comments: PS: Also, when you respond, can you please write "DR. BOWERS--- PLEASE CHECK-- FIRST RESPONSE" This will ensure that I read it as soon as possible so that you can get it out to the student as soon as possible. The system does not distinguish between first and second responses when it emails me, so this is the only "fix" that I can use to get around the bug. Thank you,

Megan,
Thank you for your response. In your answer to part "a", what do the 1/4 and 3/4 represent? Try finding the length of the entire stilt to help you reach the correct answer. Then, use this information to find the answer to part "b".
Once you find the answers to parts "a" and "b", your answer to the challenge problem might change. I am looking forward to your revisions.

Instructor Comments: Kevin,
Your assessment of the student's confusion is absolutely correct. However, I think you need to really help this child a bit more. It appears from her response that she believes that the 1/4 and 3/4 represent feet, instead of fractional quantities of the pole. Therefore, I think you need to elaborate more clearly on the relationships in the problem (that is, explain how fractions relate to the 5 feet still dry and maybe even give her a hint as to how the 5 feet equates with 2/3 of the pole and ask her then what 1/3 equates to find the length of the pole above the ground. Also, once again, the system can't handle double quote marks, so please replace these.

Thank you for your response. In your answer to part 'a', what do the 1/4 and 3/4 represent? Try finding the length of the entire stilt to help you reach the correct answer. (HINT: Use the '5 feet' that is left dry to help find out the length of the stilt). Then, use this information to find the answer to part 'b'.
Once you find the answers to parts 'a' and 'b', your answer to the challenge problem might change. I am looking forward to your revisions.

the 1/4 means the part of the pole that was in the ground and the 3/4 means the part of the pole that was covered in the year 2002. That is what 3/4 and 1/4 mean

Mentor Reply: Megan,
Thanks again for responding. I now see how you were thinking in your solution. You were on the right track and just needed to find the length of the pole, in feet. For the first part of the problem, you need to figure out how long the entire stilt is. 1/4 of the stilt is buried in the ground. The next piece of the stilt was drenched with water during the storm, and that piece accounts for 1/3 of the part of the stilt that is sticking out of the ground. So, that piece is 1/3 of 3/4 of the entire stilt, or (1/3 * 3/4 = 1/4 of the stilt). So, 1/4 of the stilt is in the ground and another 1/4 was drenched in the storm, which leaves 2/4, or 1/2, of the stilt that is dry. The problem tells you that this 1/2 of the stilt is 5 feet long. When you know this, you can figure out that the whole stilt is 10 feet long. 1/4 of it is sticking in the ground, so 3/4 of 10 feet is 7.5 feet (which is the length of the stilt that is sticking out of the ground). Finally, you can use this information to solve the rest of the problem. Hopefully I have explained this solution clearly. If you have any final questions, please let me know. Have a great weekend!

question #1.
Answer: 330 calories
I got 330 calories because since there was 14 grames of fat in the cheese burger and one gram of fat has 9 calories, I just took the 14 grames of fat in a cheese burger and the 9 calories of fat in a gram and timesed them to gether to get 120. Then I took the 36 grams of carbohydrates and timesed that by the number of carbohydrates (4) and I got 144. But I still wasn't done. then I had to take the 15 grames of protien in the cheese burger and times it by the number of protien in 1 gram (4) and I got 60. Then to finish of the problem I added 120, 144, and 60 to get 330. Thats how I got my answer to #1
question #2
Answer: 6 2/35
I took the number 330 because that is how many calories that were in the cheese burger and divided it by 2000. I used 2000 because that is how many calories that are in the RDA. So I divided those two numbers to get 6 20/330. But by simplifing the number by 10 then I got 6 2/33
question #3
Answer: 14/55
Since the cheese burger was 120 percent fat I used 120 and put it over 330 because that is the number of calories total. I made the problem look like this> 120/330. The next stpe was simplifying those two numbers. I used 5 to simplify the fraction because 5 was the closest number for both of them. Then I got 14/55
challenge
Answer: 27
The reason I said 27 was because 1/3 of 27 is 9 and 3/4 of 9 would be about 5, then 1/2 of 5 is close to 3. which means that there were 3 mcnuggets left. That is why I said 27.

Instructor Comments: Kevin, Please respond as soon as possible. As a reminder, please recall that initially there was a question asking how many calories are in the cheeseburger, but that was inadvertently deleted. So, I think I would write back and say that she is correct, there are 330 calories in the cheeseburger, but there are currently two questions: --- [and describe each]. See my comments regarding Chandler's inversion of the fraction and write a similar response to Megan.--Dr. Bowers

Mentor Reply: Megan,
Thanks for your response. Your methods for finding the amount of calories in the cheeseburger are correct. That question was deleted by the system, so now only the last two questions are being asked.
So, my question is why did you do 2,000/330? When you get an answer of 6, that means that she ate about 600% of what is allowed by the RDA! (HINT: In order to find the fraction of what she ate for the day, you need to put the amount of calories from the cheeseburger over the whole amount of calories suggested by the RDA).
Your thinking for the next question is correct. However, check your numbers again because you have 120 for the number of calories from fat (HINT: Check what 9 times 14 is again).
For the challenge problem, try working backwards to figure out the challenge problem and you are on your way! I am looking forward to reading your next response.
Kevin
