A local bookstore is selling each of their books at the same price. Jamal bought 
 books for a total of 
.

Which of the following equations represents the cost, 
, in dollars for 
 books

To determine the equation that represents the cost $ C $ in dollars for $ n $ books, given that each book costs the same amount, we can follow these steps:

1. Let $ p $ represent the price of each book.
2. If Jamal buys $ n $ books, the total cost $ C $ is calculated by multiplying the price per book $ p $ by the number of books $ n $.

Thus, the equation representing the cost $ C $ for $ n $ books is:
\[ C = p \cdot n \]

This equation means that if you know the price per book and the number of books purchased, you can find the total cost by multiplying these two values together.

Would you like more details or have any questions about this solution? Here are some related questions you might find interesting:

1. If each book costs $12 and Jamal buys 5 books, what is the total cost?
2. How many books can Jamal buy with $60 if each book costs $10?
3. If the total cost for 8 books is $64, what is the price per book?
4. Jamal bought 7 books for a total of $91. How much did each book cost?
5. If the price per book increases by $2, how does the equation change?
