if value is between

Hi, 

I created one more table with unique data in it. 

But I still cannot make the data "loop". 

For example I have some product (computer programme f.e.) and it has not been used 24/7 but only 8 hrs. And the payment is only for these 8 hours. 

And there is a pricing list that depends on amount of product consumed, f.e. it the product is consumed 0-5 then price is 0.003. If product is consumed 5-10, then price is 0.004. And it is in the table marked as Minimal value. 

What I need is to see the pricing client gets, if he has used certain amount of product.
https://www.dropbox.com/s/ifalsxwpqtn967i/sample.xlsx?dl=0 in this sample you can see that I have different products, but I cannot link the price to them, as there are different amounts of use. 
And I write a formula IF bigger than 0, "price", IF bigger 5, "price".. I think I will have to rewrite code in case when new prices / minimal values will come in! IS it possible to create some kind of indexing and then set the price? 

Will wait for your help. Best, Ani
