Final answer:
The stockholders' equity in 20×2 is $175,000.
Step-by-step explanation:
In 20×1, Lee Chan had $40,000 in liabilities and $160,000 in stockholders' equity. In 20×2, the assets increased by $20,000 and the liabilities increased by $5,000. To calculate the stockholders' equity in 20×2, we need to subtract the liabilities from the total assets. So, $160,000 (stockholders' equity in 20×1) + $20,000 (increase in assets) - $5,000 (increase in liabilities) = $175,000.
