To find the average of the numbers 26,315, 20,200, 24,880, and 28,805, follow these steps:
1. Add all the numbers together:
\[
26,315 + 20,200 + 24,880 + 28,805 = 100,200
\]
2. Divide the sum by the number of values:
\[
\text{Average} = \frac{100,200}{4} = 25,050
\]
Therefore, the average price of the four numbers is **25,050**.
