The cost for direct labor is $35 per hour and the cost of the direct materials used by Job 757 is $1,500.
How much manufacturing overhead would be allocated to Job 757 using the departmental overhead rates?

= Departmental overhead rate per machine hour × number of machine hours + departmental overhead rate per direct labor hour × number of direct labor hours

= $40 × 12 hours + $25 × 9 hours

= $480 + $225

= $665

We use only the departmental overhead rate for finding out the manufacturing overhead account
