Hi Rodrigo,

Check out Enumerable#find.
http://ruby-doc.org/core-2.0/Enumerable.html#method-i-find

With a hash it'll look something like this:
hsh.find { |key, value| value[:yourkey] == yourvalue }

That should get you on the right track.

Cheers,
Jason

I am beginning to adventure in Ruby and I need to find in this array of<br>
hashes the id with the value of 3 and get its price. What would be the<br>
easiest way to do it?<br>
<br>
Thanks<br>
