The following cost functions were developed for manufacturing overhead costs:

Manufacturing Overhead Cost Cost Function

Electricity $200 + $20 per direct labor hour

Maintenance $400 + $30 per direct labor hour

Supervisors' salaries $20,000 per month

Indirect materials $16 per direct labor hour

If January production is expected to be 2,000 units requiring 3,000 direct labor hours, estimated manufacturing overhead costs would be what?
