Answer:
55 pages
Step-by-step explanation:
Knowing that the <em>book holds 600 cards and 6 cards/page</em>, we can tell that there are <em>100 pages</em>.
From that, we know that 45% are empty, which means <em>55% of all of the pages have cards</em>.
55% of 100 is 55. Therefore, 55 pages have baseball cards.
