Final answer:
The amount of cash used by financing activities for Howell, Inc. in 2018 was $260,000.
Step-by-step explanation:
To calculate the amount of cash used by financing activities, we need to look at the changes in long-term liabilities and equity accounts. In this case, the gain on early extinguishment of debt is a noncash item and should be excluded. The increase in the deferred tax liability and treasury stock accounts represents cash used. Therefore, the amount of cash used by financing activities for Howell, Inc. can be calculated as follows:
Cash used by financing activities = Increase in deferred tax liability + Increase in treasury stock
= $20,000 + $240,000 = $260,000
So, the correct answer is d. $260,000.
