Answer
Jack will pay \$64 for 16 books.
Solution
To solve the problem, we need to determine how much Jack will pay for 16 books given that the sale offers 3 books for \( \$ 12 \).
### Step 1: Find the price per book
First, we calculate the price of one book. Since 3 books cost \( \$ 12 \), we can find the price per book by dividing the total cost by the number of books:
\[
\text{Price per book} = \frac{12}{3} = 4
\]
### Step 2: Calculate the total cost for 16 books
Now that we know the price per book is \( \$ 4 \), we can find the total cost for 16 books by multiplying the price per book by the number of books:
\[
\text{Total cost} = 16 \times 4
\]
### Step 3: Perform the calculation
Now, we perform the multiplication:
\[
\text{Total cost} = 16 \times 4 = 64
\]
### Final Answer
Jack will pay \( \$ 64 \) for 16 books.

To find out how much Jack will pay for 16 books, we first determine the cost per book. Since 3 books cost $12, the cost per book is \( \frac{12}{3} = 4 \) dollars. Therefore, for 16 books, Jack will pay \( 16 \times 4 = 64 \) dollars. In this scenario, it helps to break down the problem into smaller parts. First, calculate the price for one set of 3 books, then determine how many sets fit into 16 books. It’s a common mistake to multiply directly without realizing the price can be calculated in bulk, so always check for that shortcut!
