The question asks for the average sales of all merchants in the year 2013, and the chart above seems to provide relevant data. Let me analyze it:

### Step 1: Extracting data for 2013
From the graph, 2013 is represented by the three bars to the left. Each bar likely represents the sales in different months or quarters of that year. I will estimate the values for 2013 based on the bar heights in comparison with the y-axis (which is labeled in thousands).

- **January 2013**: Approx. 85,000
- **March 2013**: Approx. 92,000
- **May 2013**: Approx. 95,000

### Step 2: Calculating the average
The average sales for 2013 can be calculated by summing these values and dividing by the number of data points (in this case, 3).

\[
\text{Average} = \frac{85,000 + 92,000 + 95,000}{3}
\]

\[
\text{Average} = \frac{272,000}{3} = 90,666.67
\]

### Step 3: Matching the closest answer
The closest answer to this average is **$92,500.00**, which seems reasonable based on the data available.

3. How would seasonal trends affect the interpretation of sales data like this?
4. How can outliers impact the calculation of averages?
5. Why is it important to consider the sample size when calculating averages?

**Tip**: When analyzing bar graphs, ensure you carefully compare the heights of the bars relative to the labeled axis for accurate data extraction.
