To find the cost per book, we need to divide the total cost by the number of books. Here are the steps: 1. **Identify the total cost and the number of books:** - Total cost = \( \$ 40 \) - Number of books = \( 20 \) 2. **Calculate the cost per book:** \[ \text{Cost per book} = \frac{\text{Total cost}}{\text{Number of books}} = \frac{40}{20} \] 3. **Perform the calculation:** \[ \text{Cost per book} = 2 \] Thus, the cost per book is \( \$ 2.00 \). It seems there was a misunderstanding in your initial statement of \( 0.50 \) per book; the correct answer is \( 2.00 \) per book.
