"Three a week."

Translation: Τρία ανά εβδομάδα.

Ανά didn't appear in the hints, and this is a new word to me. (I have a screenshot, but I don't know how to show it here.)

Wouldn't "Τρια τη εβδομαδα" be acceptable?

[panagiotis_ts]

Your translation is almost correct. One never says "τη εβδομάδα" but "τη βδομάδα" (you have to omit the "ε"). It's the same as "μέρα" and "ημέρα" (= day). :-)

What is wrong with using για instead of ανά?

[troll1995]

Τρία για βδομάδα just makes no sense in Greek, τρία για μία βδομάδα means "three for a week" (in the sense of: How many shirts do you need for the trip? I need three for a week). Three a week can be Τρία την βδομάδα or τρία ανά βδομάδα.
