Final answer:
The estimated direct labor-hours at the beginning of the year used to determine the predetermined overhead rate were 35,650 hours, as this is the amount that, when multiplied by the predetermined overhead rate, equals the estimated manufacturing overhead.
Step-by-step explanation:
The student is asking about finding the estimated direct labor-hours used to determine the predetermined overhead rate in cost accounting.
We are given that the estimated manufacturing overhead is $802,125, the actual manufacturing overhead is $775,000, and the overhead was overapplied by $41,075. To find the estimated direct labor-hours, we need to calculate the predetermined overhead rate and then use it to find the estimated hours.
First, determine the applied manufacturing overhead, which is actual overhead plus overapplied amount: $775,000 + $41,075 = $816,075. The predetermined overhead rate is then the applied overhead divided by actual labor hours: $816,075 ÷ 36,270 hours = $22.50/hour.
Now, using the predetermined overhead rate and the estimated total manufacturing overhead, we calculate the estimated direct labor-hours: $802,125 ÷ $22.50 per hour = 35,650 hours.
