I am not sure how to post a question but I started going over the book and I like it a lot. I got stuck with the Enum.each exercise.
I do: apply_tax = fn price → " Price: #{price} - tax: #{price*0.12}" and when I check it alone it works fine
I then do:Enum.each([12.5, 30.99, 250.49, 18.8], apply_tax ) and it just print 
I also tried: Enum.each([12.5, 30.99, 250.49, 18.8], fn(n) → apply_tax.(n) end ) with same results please help. Also how do I post regula questions on the forum? I could not find it like onn other forums?
Thank you Amos Madanes
