The textbook...

1) Hi, my name is ********* from your morning class of MAT 267 MWF 9:00-9:50 A.M. I know that you have listed the book title online but just as a confirmation, is the book...

Well, the cover looks good, but as you know it's a mistake to judge the book by the cover.

2) Dear Dr. Taylor,
      I have the required textbook for MAT 266, and I never used the online code. This textbook looks nearly identical to the one listed in your class requirements, and I was wondering if I could use it instead of buying the new one.  I will be bringing my old textbook to class tomorrow, so if you are not sure without looking at it, I would appreciate it if you could see if it will work. 
      Thank you in advance.

OK, I'll take a look.  I think it will be fine, but better to make sure.

3) I have an ASU Calculus book from last semester, and the author is James Stewart, but the code doesn't match the one online, and the cover is different than the one you showed in class. I'm not sure if I have the right book.

Yeah, I think you have the wrong book. Was it from the 266 course or the 271 course?
