    Danny buys 5 books at $34 each and pays for them with 10-dollar bills. How many $10 bills did it take?

    Calculate his total bill:
    Total bill = Number of books * cost per book
    Total bill = 5 * 34
    Total bill = 170

    Now calculate the number of 10-dollar bills he used:
    10-dollar bills used = Total bill / 10
    10-dollar bills used = 170/10
    10-dollar bills used = 17
