Would you like to eat apples?

I imagine a scene where my mother comes up to me and asks me if I want some apple slices, and I tell her I’m fine.

My first thought is:

母: りんごをたべたい？
私: いいえ、結構だ。

But I’m wondering if I’m translating too directly from English and or missing nuance.

Based off patterns I’ve seen on natural speech my best guess would be something more like,

母: りんごを食べるの？
私: ううん。結構よ。
