Answer
The cost per book is \$2.00.
Solution
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.

Simplify this solution Beyond the Answer
To find the cost per book, simply divide the total cost by the number of books. Here, Miss Chen spent $40 on 20 books. So, it’s \( \$40 \div 20 \text{ books} = \$2 \text{ per book} \). For those who may calculate quickly, remember that unit rates are always derived by taking the total amount and dividing it by the number of items. This offers a clear picture of the cost per individual item, helping in budgeting or comparing prices at sales!
