Question

Deborah has 104 baseball cards. She gave 16 baseball cards to her brother Corey. Then she put the remaining baseball cards in an album with 9 baseball cards on each page. How many pages of the album did Deborah use to store all of the baseball cards? Explain your thinking.

Answer 1

She used 9-10 pages in total.

Step-by-step explanation: Once she gave away 16 cards, she was left with 88. If each page fills up with 9 cards it would take her around 9 pages to put 81 cards, so she would have a remainder of 7 cards so she would end up needing 1 more page that will have 7 cards and not 9.
