Why do you post the same question again?

And why does the stupid bot answer Yes one time and No the next?
Answered by Bot
No, Travis' answer is not correct. Mr. Roberts earned $20 from selling two books, not from selling each book. Therefore, the correct answer would be $10, which is the amount Mr. Roberts earned from selling each book.
