Final answer:
Dr. Turk can buy 14 books and have $5 left over.
Step-by-step explanation:
To find out how many books Dr. Turk can buy and how much money he would have left over, we need to divide the total amount of money he has by the cost of each book. Dr. Turk has $145 and each book costs $10. Therefore, the number of books he can buy is $145 divided by $10, which is 14 books.
To find out how much money he would have left over, we need to subtract the cost of the books from the total amount of money he has. 14 books cost $10 each, so the total cost of the books is 14 multiplied by $10, which is $140. Therefore, Dr. Turk would have $145 - $140 = $5 left over.
