The New Generation Company applies manufacturing overhead to jobs on the basis of machine hours used. Overhead costs are expected to total $950,000 for the year, and machine usage is estimated at 130,000 hours.

In the first six months of the calendar year, $400,000 of overhead costs was incurred and 60,000 machine hours were used. For the remainder of the year, $500,000 of additional overhead costs is incurred. Actual machine hours exceeded expected machine hours by 10% of the original estimate.
