Assume that in August 2019 the U.S. had $9 billion in clothing retail sales. Using the information in Graph B, calculate the amount of clothing retail sales in August 2020 in billions of dollars. Round your answer to 2 decimal places.
Note: answering in billions means that if you think the answer is $4 billion, you should answer “4” in the box below.

To find the clothing retail sales in August 2020, we need to know the percentage change in sales from August 2019 to August 2020, which is usually represented in a graph like Graph B. Since you mentioned a graph (Graph B), let’s assume that Graph B shows the percentage change.

Here's the step-by-step approach to solve this:

1. **Identify the 2019 sales amount**: It is given as $9 billion.
2. **Find the percentage change**: Let’s denote this percentage change as $ P $. This value should be derived from Graph B. For this example, let’s assume Graph B shows a percentage change of $ P\% $.
3. **Calculate the 2020 sales amount**:
   - The formula to calculate the new sales amount using the percentage change is:

     \[
     \text{Sales in 2020} = \text{Sales in 2019} \times \left(1 + \frac{P}{100}\right)
     \]

4. **Substitute the values**:
   - Use $ 9 $ billion as the sales in 2019.
   - Substitute the percentage change $ P $ derived from Graph B.

Since you haven’t provided the exact percentage from the graph, I can't calculate the exact sales amount for 2020 without this information. However, if you provide the percentage change, I can quickly compute the sales in 2020 for you.

### Example Calculation:
If Graph B shows a 10% increase, then:

\[
\text{Sales in 2020} = 9 \times \left(1 + \frac{10}{100}\right) = 9 \times 1.10 = 9.9
\]

So, the answer would be **9.9 billion** dollars.

Please provide the exact percentage from Graph B, and I can complete the calculation accurately! 

Would you like to proceed with this example, or do you have the percentage from Graph B?

### Follow-up Questions:
1. What was the exact percentage change shown in Graph B for August 2020?
2. How can we interpret a negative percentage change in this context?
3. What would happen if the percentage change was 0%?
4. How does inflation impact retail sales comparisons year-over-year?
5. How would you calculate the percentage change if given two sales amounts?

### Tip:
Always pay attention to whether the change is an increase or a decrease when working with percentages in problems like this.
