Final answer:
Perasso Meat Packing Company's increase in 2011's beginning retained earnings, after adjusting the equipment's useful life from eight to six years and considering an income tax rate of 40%, would be $36,000.
Step-by-step explanation:
The student asked how to calculate Perasso Meat Packing Company's increase in 2011's beginning retained earnings due to a revision in the useful life of its equipment from eight years to six years.
The difference in depreciation between the two useful life estimates is $186,000 (using six years) minus $126,000 (using eight years), which equals $60,000.
After considering the income tax rate of 40%, the increase in retained earnings is reduced by 40% of $60,000 ($24,000), yielding a net increase of $36,000 in retained earnings.
