It makes no sense. (by the way this is for my bro)

First the 20% discount is applied, then the 10% discount is applied onto the new price.

So Zoe saves 20% initially. That means the price is now 80% of what it was.

She receives a further 10% discount off this new price. 10% of 80% is another 8% saved, with respect to the original price.

20% + 8% = 28%.
