I'm grading some homework (I'm a TA) and one of the word problems is rather vague. The problem is very short, it asks one to calculate a property of two objects, and then asks "how much more" for one of the objects. When I took the class I considered this as asking for the difference between quantity A and B. The TA when I took the class end up taking off 40% of what the problem was worth. The correct answer was to calculate a ratio. The wording, in my opinion, was too vague, and for me, when someone asks "how much more" one object is with regard to another, that's asking for a difference of some sort. Now that I'm in the TA position, I don't necessarily want to punish people for interpreting problem like I originally did. I'm going to give full credit for anyone that calculated a the difference correctly regardless of what anyone posts here. Indeed, by the time anyone replies the homework will be graded and out of my hands. So, just curious, how would any of you handle this?
