Final Answer:
The company's net income will decrease by $9,330. (Option d is correct.)
Step-by-step explanation:
Tax effect: While a discontinued operation gain is considered income, it's treated differently for tax purposes compared to ongoing operations. A 30% tax rate applied to the gain ($31,100 * 0.3) results in a tax liability of $9,330.
Net income effect: This tax liability reduces the overall net income. Therefore, instead of increasing by the full amount of the gain, the company's net income will decrease by the tax effect:
Net income decrease = Discontinued operation gain - Tax liability
Net income decrease = $31,100 - $9,330 = $21,770
Therefore, although the discontinued operation is technically a gain, the tax implications lead to a decrease in net income by $9,330.
Option d is correct.
