Intercontinental Company bases its predetermined overhead rate on direct labor hours. At the beginning of the current year, the company estimated that its manufacturing overhead would total $440,000 during the year. During the year, the company incurred $400,000 in actual manufacturing overhead costs. The manufacturing overhead account showed that overhead was under applied by $16,000 during the year. If the predetermined overhead rate was $40.00 per direct labor hour, how many hours were worked during the year?
