To find the mean profit from the sales, follow these steps:
1. Add the profits together:
\[
10,126 + 9,999 + 12,398 + 12,007 + 4,567
\]
Performing the addition step-by-step:
- \(10,126 + 9,999 = 20,125\)
- \(20,125 + 12,398 = 32,523\)
- \(32,523 + 12,007 = 44,530\)
- \(44,530 + 4,567 = 49,097\)
Thus, the total profit is \(49,097\).
2. Count the number of sales:
There are 5 sales.
3. Calculate the mean:
\[
\text{Mean} = \frac{\text{Total Profit}}{\text{Number of Cars Sold}} = \frac{49,097}{5} = 9,819.4
\]
Therefore, the mean profit for the sales is **$9,819.40**.
The correct answer is:
**D) $9,819.40**
