Answer:
Predetermine overhead rate as a percentage of direct labor cost is 120%
Step-by-step explanation:
To calculate the predetermined overhead rate, we first need to determine the total overheads under the balance of $3980 for two jobs.
The total cost of both jobs which are uncompleted equals,
Total cost both jobs = (660 + 560) + (460 + 740)
Total cost both jobs = 1220 + 1200 = $2420
Thus, the overhead cost involved in both jobs is,
Total Overhead cost = 3980 - 2420 = $1560
This total overhead of $1560 has been absorbed on the basis of a predetermine overhead rate based on the direct labor cost. The total direct labor cost involved under both uncompleted jobs is,
Total direct labor cost both jobs = 560 +740 = $1300
So, the predetermined overhead rate is,
Overhead rate = Total overheads / total direct labor cost
Overhead rate = 1560 / 1300
Overhead rate = $1.2 per $1 of direct labor cost
Expressed as a percentage of direct labor cost, it is:
% Overhead rate = 1560 / 1300 * 100 = 120% of direct labor cost
