Wait just a minute. This is your homework you should study for, not just get other folks to give you answers without you taking time to understand the lesson. Put your nose in the book and put the computer down. Either that or call another student from your class and work together. You'll thank me when you can do this on your own, unless you want to just be one of the guys messing up people's cars at Jiffy Lube.
