Sloan Manufacturing Corporation applies manufacturing overhead on the basis of 120% of direct labor cost. An analysis of the related accounts and job order cost sheet indicates that during the year total manufacturing overhead incurred was $420,000 and that at year-end Work in Process Inventory, Finished Goods Inventory, and Cost of Goods Sold included $60,000, $40,000, and $300,000, respectively, of direct labor incurred during the current year.

a) Determine the over-applied manufacturing overhead at year-end (assume it is significant).

b) Prepare a journal entry to record the disposition of the over-applied manufacturing overhead.
