Respuesta :
Since there are 9 hockey cards per page and it holds 900 hockey cards you can multiply 9 by 68 to get the total of 612 hockey cards. Then take 900 and subtract 612 from it and you should get 288 hockey cards in the album. Then divide that number by 9 to get the total number of pages filled 288/9=32 pages filled
Answer:
The answer is 288 pages are filled with hockey cards
Step-by-step explanation:
First, you need to figure out what percentage of the album is full which is 32% So, with that 32% you figure out how many pages that is. So you would find 32% of 900 which is 288 therefor, that would be your answer.
