"How much is this?"
Translation:Πόσο είναι αυτό;
As I wasn't sure, I looked at the clue. Following the suggestion I received from one of the moderators yesterday, I chose the top (in this case, the only) choice for translating this sentence. What I wrote was "Πόσο κάνει αυτή;", which was the only choice offered in the clues. Then I was told that it's wrong, and I should have written "Πόσο είναι αυτό;". Which is it? Keep in mind that Πόσο είναι αυτό; wasn't even an option listed.
