Sammy has eight chains with seven links each. He wants to connect all these chains to make a totally awesome necklace that's a single loop. The jeweler says he can open and close a single link for $2.
As shown below, Sammy could open an end of each of the eight chains to make one long necklace that's a single loop. However, that would cost $16, and the truth is there's a cheaper way to get the same results. Using the cheapest method possible, how much will it cost to make Sammy's necklace?
Give it another try.
Take one of Sammy's seven-link chains, break each link apart, and use them to connect the remaining small chains together. You can see this method illustrated here.
If Sammy uses this method, he can get the necklace of his dreams for only $14.
