Answer 1

To calculate the total bushels of corn produced by the farmer over her first 4 years, we first find out how much she produces each year given the 5% increase.

1. **First Year:**
- Production = 40,000 bushels

2. **Second Year:**
- Production = 40,000 * (1 + 0.05) = 40,000 * 1.05 = 42,000 bushels

3. **Third Year:**
- Production = 42,000 * (1 + 0.05) = 42,000 * 1.05 = 44,100 bushels

4. **Fourth Year:**
- Production = 44,100 * (1 + 0.05) = 44,100 * 1.05 = 46,305 bushels

Now we sum the total production over the four years:

\[
\text{Total Production} = 40,000 + 42,000 + 44,100 + 46,305
\]

Calculating this step-by-step:

- \(40,000 + 42,000 = 82,000\)
- \(82,000 + 44,100 = 126,100\)
- \(126,100 + 46,305 = 172,405\)

Therefore, the total bushels of corn produced in her first 4 years of farming is **172,405 bushels**.

The correct answer is:

**172,405 bushels**
