14. Number Sense Jorge collects sports

cards. He displays his cards in an album.

There are 72 pages in the album. Each

page holds 9 cards. Find the number of

cards in the album if half of the pages

are full and the rest are empty.

324 cards.

Step-by-step explanation:

Hi, to answer this question we have to multiply the number of pages in the album (72) by the number of cards that each page holds (9):

Mathematically speaking:

72(9) = 648 cards in the album

Since half of the pages are full, we have to divide the previous result by 2.

648/2 = 324 cards
