Advanced Pricing setup

Hello,

Is it possible to do advanced pricing setup, fixed extended amount but unit price should vary based on quantity.

E.g.: Quantity 1 to 5EA -> Extended amount always should be $100.

expected unit price is

If Quantity is 1EA  then Unit price= $100/1 = $100

Quantity 2EA -> Unit price = $100/2 = $50

Quantity 3EA -> Unit price = $100/3 = $33.33

Quantity 4EA -> Unit Price = $100/4 = $25

Quantity 5EA -> Unit Price = $100/5 = $20

Thanks,
