Adding quantities per product ie. 1, 5, 10, 20, 50, 100 and applying discounts per quantity

Hi all,
Hoping there's a simple way to approach this.
My client is producing, let's call them personalised printed trading cards and wants to offer customers a way to purchase multiples of the same card. ie. 1, 5, 10, 20, 50, 100 and then be able to apply a discounted cost for each of those specific quantities. 

We don't need to worry about the personalisation or upload of the cards, we're just wanting a way to add specific quantitiy options, and then apply a specific cost to these options.

ie;

1 = $10
2 = $15
5 = $35
20 = $175

Is this possible to do, or is there a workaround?

Thanks in advance.

Thanks Paul, I figured that was likely the case.
