Answer: There are 48 blue cards in the game.
Step-by-step explanation:
Given: In a certain card game, for every 4 blue cards, there are 3 yellow cards.
Total cards = 4+3 = 7
There are a total of 84 blue and yellow cards in the game.
Number of blue cards = [tex]\dfrac{4}{7}\times 84=4\times12 = 48[/tex]
Hence, there are 48 blue cards in the game.
