D. 24500

Answer

To solve the expression \( 421 \times 0.9 + 130 \times 101 + 10000 \), we will break it down into steps.

### Step 1: Calculate \( 421 \times 0.9 \)
To find this product, we can multiply:
\[ 421 \times 0.9 = 378.9 \]

### Step 2: Calculate \( 130 \times 101 \)
Next, we calculate this product:
\[ 130 \times 101 = 13130 \]

### Step 3: Add the results from Step 1 and Step 2
Now, we will add the results from Step 1 and Step 2:
\[ 378.9 + 13130 = 13508.9 \]

### Step 4: Add \( 10000 \) to the result from Step 3
Finally, we will add \( 10000 \) to the result from Step 3:
\[ 13508.9 + 10000 = 23508.9 \]

### Step 5: Approximate the final result
To approximate \( 23508.9 \), we can round it to the nearest hundred:
\[ 23508.9 \approx 23500 \]

### Final Answer
Thus, the final answer is approximately \( 23500 \).
