2. At the end of the year, Jenkins Corporation had $120,000 in the factory overhead account and $100,000 in the applied factory overhead account. Mark Gibbs, the controller, has decided that the overhead difference is too large to close with the Cost of Goods Sold account alone. He decides it is best to charge the overhead difference to the Work in Process, Finished Goods, and Cost of Goods Sold accounts. The balance of these three accounts is:

Work in Progress $30,000

Finished goods $60,000

Cost of goods sold $210,000

How much of the overhead difference will be charged to the Cost of Goods Sold account?

3. Lynch Audio produces stereo components for a major manufacturer of car stereos. You currently use the machine-hours method to apply factory overhead to production. The information for the previous year is as follows:
