At the beginning of the month, Evan had $24 in his account at the school bookstore. First he bought some notebooks and pens that cost $16. Then he deposited some more money and his account balance was $28. Then he bought a book for English class that cost $34. Then he deposited exactly enough money so that he paid off his debt to the bookstore. How much money does Evan have in his account at the school bookstore now?
