B$.$ Now Amitabh makes a commitment to all of his customers: he WILL get them the shampoo if they want it$,$ no matter what! He is able to do this because he will expedite Pumpkin Spice Shampoo from his supplier at $$15$ per bottle cost to himself $($this includes the expedited shipping cost of $$12\mathrm{.}80$ plus the $$2\mathrm{.}20$ cost of the product itself$).$ The cost is high, but he thinks his future business depends on taking such risks, and ensuring customer loyalty. This means that if demand is $101,$ and if he ordered $100$ initially, then he would need to expedite $(101100=)1$ bottle, and pay $$15$ to expedite this one bottle; we would sell it to the $101$st customer for $$8$ at a loss of $$7.$
