Another weekend with another new puzzle. This puzzle is pretty straightforward. And as always you will solve it in no time. No more chit-chat. Now read this puzzle carefully and answer the below question.
Rick is a genius mechanical engineer working on world changing project in his own garage. To continue on his project work he needs a long iron chain with at least 15 links.
Rick searches his garage for the long chain. But instead of a long chain he found 5 chains with 3 links each. After the failed search Rick decided to use those 5 chains to form a long chain. In order to do that, he needs to open and then weld the links.
As soon as Rick decided to link those chains, he realized opening a link costs $1 and wielding a link costs $3. At this critical stage of the project he wants to save as much money as he can.
What is the minimum amount Rick has to spend to make the long chain?
