Luis buy 3 packs of base ball card and 5 packs of pokemone card
Since each pack has 8 card, then;
To get the total number of cards;
We will multiply each pack by the number of cards and then add the total number of cards together
That is;
Number of pack of base ball bought by Luis is 3
To get the total number of cards in the 3 packs, we will multiply the 3packs by 8 since there are 8 cards in each pack
Number of base ball cards bought by Luise= 3 x 8 = 24 base ball cards
Similarly;
Number of packs of pokemone card bought by Luis is 5
To get the total number of pokemone cards bought by Luis, we will multiply 5 by 8 since each park contains 8 cards
That is;
Number of pokemone cards bought by Luis = 5 x 8 = 40 pokemone cards
To get the total number of cards, we will add both the total number of baseball and pokemone cards together;
Total number of cards bought by Luis = 24 + 40 = 64 cards
Therefore: Luis bought 64 cards
