Answer:
B. $29,000
Explanation:
The cashflow from operating activities is calculated as below:
Cashflow from operating activities = Net income + Depreciation - Working capital investment
= Net income + Depreciation - (Change in inventories + Change in account receivables - Change in account payables)
Putting all the number together, we have:
123,000 = Net income + 38,000 - [(-27,000) + 31,000 - 48,000 - 12,000),
Solve the equation we get Net income = 29,000.
Based on the information given the predetermined overhead rate is 31.89 per direct labor hour.
<h3>Predetermined overhead rate</h3>
Using this formula
Predetermined Overhead rate = Estimated manufacturing overhead / Estimated total labor hours
Let plug in the formula
Predetermined Overhead rate = [$1,026,260 + (46,000×6.25)] / 41,200
Predetermined Overhead rate =1,313,760/ 41,200
Predetermined Overhead rate = 31.89 per direct labor hour
Inconclusion the predetermined overhead rate is 31.89 per direct labor hour.
