Re: Making a necklace
Funny how when I posted this puzzle(and it was the "exact" same puzzle!)
(in the "chain puzzles" thread) with some harder ones aswell, no one answered. So what did I do wrong?

I meant $20 not 18. Man, was my brain out that day.

Re: Making a necklace
The answer is $8 Just break up one chain into it's 4 links and put them between the remaining four and then close them.
Look at my thread chain puzzles for some harder ones:D
