The answer to last week’s challenge is,  Q: What can you hold in your right hand, but never in your left hand?

A: Your left hand.

This week’s challenge is:

Q: You’re rummaging around your great grandmother’s attic when you find five short chains each made of four gold links. It occurs to you that if you combined them all into one big loop of 20 links, you’d have an incredible necklace. So you bring it into a jeweller, who tells you the cost of making the necklace will be $10 for each gold link that she has to break and then reseal. How much will it cost?

The answer along with a new challenge, next week.

Have an excellent weekend!
