Question

If R= (photo)

Answer 1

You have to integrate first. Afterwards, I don't recall, but I think you have to divide the answer by x (the number of units) and make C = 0 (because R (0) = (0) )

Answer 2

So I guess p(x) = 250 - 9x

Answer 3

how confident do you feel in that answer? haha @bmp here are all the choices

Answer 4

It can't be either of the two last ones. I am somewhere near 60% confidence in the first, but I learned Calc I as a self-learner in HS, so I don't really remember price-profit relations. Anyway, it is similar to this answer at least: http://answers.yahoo.com/question/index?qid=20090420221744AAjNOFk
