Smith pays 1000 on November 9 and cashes in the bond on the following January 1. What is his equivalent effective annual rate of interest for his transaction?

The answer should be .1365. I have been trying many different things, but I cannot seem to get it. Any input on how I can go about solving this problem will be greatly appreciated.
