Answer:
The balance in stockholders' equity at the end of year 2 is $31,000
Explanation:
For computing the balance in stockholder equity at the end of year 2, first, we have to compute the balance for year 1  which is shown below:
Year 1 equity balance = Issue of stock + Net income
                                      = $20,000 + $5,000
                                      = $25,000
Now, year 2 balance would equal to
= Year 1 balance + Net income - Dividend paid
= $25,000 + $10,000 - $4,000
= $31,000
Hence, the balance in stockholders' equity at the end of year 2 is $31,000
