Four Chains: Creative problem solving with creative approach

Another creative problem solving exercises which can be answered by creative thinking techniques and creative approach. A businessman brought back from Europe four pieces of chain in solid gold, each consisting of three links.

He wanted to keep them as an investment, but his wife felt that—joined together—the pieces would make a lovely necklace. She went to a jeweler and said, “I want you to connect these pieces to make a necklace. How much will it cost?” The jeweler laid the individual pieces of chain out in this pattern:

He told the lady, “I charge $2.50 to break a link and $2.50 to melt it together again. Since you have four corners, it will cost you $20.” The lady said, “That’s too much. Actually you can do it for $15.” The problem, then, is to construct a necklace, breaking and joining only three links. How would you do it?
