What would you pay?

I made this cake for my MIL as requested by my SIL.

She sent me the 2nd Pic as a reference but requested none of those extra details (gold splatter, stencil, numbers) and instead just to make it purple and say happy birthday.

She always pays me when she asks for cakes and for this one I asked her for $95. I keep going back n forth with telling myself it was a good deal to that's overpriced lol.

It's a simple vanilla cake with vanilla buttercream and a caramel buttercream filling.

6" with 5 layers of cake.

TIA
