The company actually incurred $247,000 of manufacturing overhead and 12,500 direct labor-hours during the period.
Required:
- Calculate the underapplied or overapplied manufacturing overhead.
- Assume the company’s underapplied or overapplied overhead is closed to Cost of Goods Sold. Would the closing journal entry increase or decrease gross margin? By how much?
