Thanks to royhaas for replying to the previous post that I made (see below). To update everyone, a poster on another site told me the correct answer is "the one with 14 circles, 8 of which are colored in". Now, I am getting interested in exposing ridiculous problems in the world of math education.
Here is a problem that was asked on a state exam for 7th grade. I would like to have anyone's opinion as to whether it should be on such a 'high stakes' test or not:
15 Ashton needs a total of $1.50 in quarters for a coin-operated car wash. He already has $0.75. Which equation can be used to find q, the number of additional quarters Ashton needs in order to have enough money for the car wash?
A 1.5 = 0.75q + 0.25
B 0.75 = 1.5q + 0.25
C 0.75 = 0.25q + 1.5
D 1.5 = 0.25q + 0.75
Does anyone have an opinion as to whether this question, along with the answer choices, is good or bad. Should it be used on a state competency exam?

---------
Someone showed me this problem. I am wondering if it has been doctored to make no sense on purpose (to prove someone's point) or if it is an actual problem.
It makes no sense to me. Has anyone seen a question like this?
Supposedly it is a question that Houghton Mifflin says is tied to the "common core standards".

14-8 is 6 in base 10. Period.

Are you saying that this problem is ridiculous? If so, I agree.
Has anyone seen this way of writing the answer to 14-8?

a poster on another site told me the answer is, "the one with 14 circles, of which 8 are colered in"

Does anyone have an opinion on the new problem that I just inserted into this thread? #15 in the original post.
The objective that the state claims this is testing is:
"Formulate problem situations when given a simple equation and formulate an equation when given a problem situation".
In my opinion the objective, as stated, can not be tested using simple multiple choice responses.
Maybe I am wrong. This is why I have added to my original post.
Anyone?
