They don't introduce variables in 1st grade, which is why I gave the answer I did.Question 1:
Let x be number of cups of food Rusty eats.
Answer: Midnight eats |4 - x| more or fewer cups of food than does Rusty.
Question 2:
Let x be the quantity of coins Erica bought.Why did I use absolute value for the first equation and not for the second? Simply to illustrate a different way of handling the answer to the problem.
Given/premise: Erica had 6 coins when she went to the coin show.
Assumption: Erica did not sell any of her coins.
Answer: Erica now has 6 + x coins.
The fact that the questions, as illustrated, do not provide enough information to yield a numeric answer does not mean there is no way to answer the questions.Among the other lies in the OP, I doubt if that is a first grade problemThey don't introduce variables in 1st grade, which is why I gave the answer I did.Question 1:

Probably third gradeI doubt if that is a first grade problem
That notion crossed my mind too; however, I'm willing to take the OP-er at his word that it is indeed a question that appears on a first grade test. I am because I have neither the will nor a way to soundly or cogently show otherwise.
The OP is rightwing propaganda attempting to discredit common core
It intentionally withheld information from previous questions that was needed to answer the problem
I doubt if a first grader has the verbal or math skills to do these problems. If they do, then common core is very, very impressive
withheld information
It also crossed my mind that there might be information elsewhere in the test and that students are instructed to use in answering the questions shown. Similarly to what I implied before, I didn't raise that possibility because I had nowhere I could take it, and no way to strongly/cogently defend its probability of being so, after having introduced it. There's just not much point -- discursively, strategically, etc. -- to publicly raising doubt when one knows one has no strong/case to support the basis for there being doubt and one knows one isn't about to put any effort into developing a strong case to that effect.
