In general, the highest price p per unit of an item at which a manufacturer can sell N items is not constant but is, rather, a function of N. Suppose the manufacturer of widgets has developed the following table showing the highest price p, in dollars, of a widget at which N widgets can be sold. Number N   Price p    250           41.50    300           40.80    350           40.10    400           39.40 Find a formula for p in terms of N modeling the data in the table. a) p = –45N – 0.014 b) p = 45N – 0.014 c) p = –45N + 0.014 d) p = –0.014N + 45
