Final answer:
The Henderson Company has underapplied overhead of $20,000 for the year 2007. This is determined by subtracting the applied overhead of $1,680,000 (based on the actual direct labor hours and the predetermined rate) from the actual overhead of $1,700,000.
Step-by-step explanation:
To calculate the amount of overhead applied using the job order costing system, multiply the actual direct labor hours by the predetermined overhead rate. Then, compare the applied overhead to the actual overhead costs to determine if there was under or overapplied overhead.
Applied Overhead = Predetermined Overhead Rate x Actual Direct Labor Hours
Actual Direct Labor Hours for 2007 = 140,000 hours
Predetermined Overhead Rate = $12 per direct labor hour
Applied Overhead = 140,000 hours x $12/hour = $1,680,000
Actual Overhead for 2007 = $1,700,000
Since the applied overhead is less than the actual overhead, we have underapplied overhead. To find the amount:
Underapplied Overhead = Actual Overhead - Applied Overhead
Underapplied Overhead = $1,700,000 - $1,680,000 = $20,000
The Henderson Company has an underapplied overhead of $20,000 for the year 2007.
