"Is it a cheap egg?"
Translation:Is het een goedkoop ei?
Yeah, it's a little tricky at first. The good news is that it's a strict rule with almost no exceptions (unlike some other parts of the language!), so once you get the hang of it, all will be well.
I guess google is wrong on this one. Google translate is: "Is het een goedkope ei?"
Yes, Google translate has the wrong translation.
I've submitted an edit, though don't know if they change it immediately.
Y.zhao-1 thanks for asking this question. I was confused also. Simius thanks for explaining te reason in a clear way.
