Let me see if I have this correct.

　　Roger

　　From your point of view, it's more important to order the units you need...

　　Roger

　　...rather than to get the cheapest price.

　　Bob

　　Right.

　　Bob

　　Most importantly, we don't want to keep a lot of back stock...

　　Bob

　　...and we're prepared to suffer a slight increase in cost for orders if necessary.

　　Roger

　　Then, may I suggest an alternative proposal.

　　Roger

　　With your past orders ranging between 600 and 800 units,...

　　Roger

　　...I would propose setting the discount rate 3% lower.

　　Roger

　　Would you be willing to accept that?

　　Bob

　　Before I respond to that offer, let me do a few calculations of my own.
