I have the following data:

QTY PRICE
<100 100
100-500 95
501-1000 90
1000-2500 85

A function that I am looking for is if I type in a quantity of 550 in a
cell, I want it to be able to retreive the correct pricing for whatever
quantity I request. In this case I want it to give me a price of 95. But I
also want to be able to use the same cell to request a quantity of 1000 and
to be able to give me back the correct price of 85.

Does anyone have a suggestion?
