Answer:
The amount of manufacturing overhead cost that would have been applied to all jobs during the period is $279,720
Step-by-step explanation:
The computation of the amount of manufacturing overhead is shown below:
= Predetermined overhead rate per direct labor-hour × total direct labor-hours
= $22.20 × 12,600 direct labors
= $279,720
Since the predetermined overhead rate is already given in the question, so there is no need to recalculate it and the other items which are mentioned are not relevant for the computation part. Hence, ignored it
