Final answer:
The equation that shows the relationship between the total number of cards Johnny has and the number of binders is: Total Cards = b × 64 - 14, where b is the number of binders.
Step-by-step explanation:
Johnny has a collection of cards in binders, with each binder holding a specific number of cards. To represent the relationship between the total number of cards he has and the number of binders, we can use the following algebraic equation:
Total Cards = Number of Binders × Cards per Binder - Cards Sold
Since Johnny has binders with 64 cards each and decides to sell 14 cards from one of them, we would write the equation as:
Total Cards = b × 64 - 14
Where b represents the number of binders Johnny has.
