comment Cost per item. Diminishing marginal discount, if you will. (Bigger discount for first few items) Optimal number of units to buy?
Thanks Nick. However, I don't think I want to minimize f'. It is clear that the smallest value of f' is where the curve is the flattest, which is at the extreme right (at 12 units) However, I am not looking for the flattest part of the curve, but where the incremental decrease is not as significant as the prior one.
