Determine the cost of using 2 different electrical devices over the course of a month.(adsbygoogle = window.adsbygoogle || []).push({});

- An item like a cellphone or something else that plugs in the wall.

Use $.20 per kilowatt-hour as your base energy cost.

I have no idea how to start this as this is a project we have to do as a prerequisite for a college course. I have been searching online and it looks like the only way to calculate this is to buy a $50 dollar Kill-o-watt. It would be great if one of you guys can help me with this without having to go out and buy something.

Also my teacher said estimating is fine too.
