Alan is a third year degree student in a local university. In October 2019, he borrowed RM2,000 from his brother to buy 50 copies of a textbook used in the previous semester from some second year degree students.

Alan transported the books to a new branch campus by car. He asked his friend, Jack, who is studying in the branch campus to help him in selling the used books to the first year degree students with a promised commission of RM10 per book. Within two weeks, they managed to sell all the 50 copies of books to different students. Alan repaid his brother RM2,000 and paid Jack commission of RM500.

Required: Explain, by reference to the badges of trade, whether the profit arising from selling books is assessable to income tax.
