Question

Jamie covers books for extra money. He makes a quarter for every dozen he covers. How many books will he have to cover to make $10.00?

Answer 1

480 books

Explanation:

There are 4 quarters in a dollar, so you know that 1 dollar is 4 quarters. You have 10 dollars, so you need to multiply the number of quarts in a dollar by the number of dollars you have:

4 × 10 = 40

You know that he gets a quarter for every dozen books and a dozen is 12. So you need to multiply the number of quarters by the number of books:

40 × 12 = 480

Jamie needs to cover 480 books to earn $10.
