It did not account for answering questions by email, it did not account for grading them.
As I wrote below, if a teacher taught 8 hours of a class at 100$ / hr, he would be paid 800$, even if he has to spend 10 extra hours grading a student.
But to be honest they weren't giving that much homework, and only one test at the end of the class. I'd estimate for every 80 hours taught, there might have been only 10-15 extra hours. Which for 100$/hr or 300$/hr is worth it.
