To find out how many pages are needed to hold all the cards, you can sum up the total number of cards and then divide by the number of cards a page can hold.
Total number of cards: \(1,173 + 592 + 445 = 2,210\) cards
Number of cards per page: \(15\) cards
Now, divide the total number of cards by the number of cards per page:
\(\frac{2,210}{15} \approx 147.33\)
Since you can't have a fraction of a page, you would need \(148\) pages to hold all the cards.
