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
