Number of hockey cards in Nick's album = 700

Number of hockey cards in each page of the album = 7

Number of pages in Nick's album :

$= \tt (700)/(7)$

$= \tt100$

▪︎Thus, the number of pages in Nick's album = 100

Percentage of album that is empty = 72%

Number of pages in the album that is empty :

$= \tt 72\% \: \: of \: \: 100$

$=\tt (72)/(100) * 100$

$= \tt (72 *100)/(100)$

$=\tt (7200)/(100)$

$\color{plum}= \tt72 \: pages$

▪︎Thus, the number of empty pages in the album = 72

Number of pages in the album that are filled :

$=\tt 100 - 72$

$\color{plum} = \tt28 \: pages$

▪︎Therefore :

Number of pages filled with hockey cards = 28
