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
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
