HW18: Chapter 18

18.4: Suggest how the SimpleInterestCalculator service could be implemented as a RESTful   service. 

This could be a basic utility service which uses the GET operation.  You could send a request to the service with the amount you have, the interest rate, and the amount of time.  It could then use the web service to make the computation and return it to you without having to create its own persistent result in a URL.
