Applying Overhead ;Computing Unit Product Cost

A company assigns overhead cost to completed jobs on the basis of 120% of direct labor. The job cost sheet for Job 413 shows that $12,000 in direct materials has been used on the job and that $8000 in direct labor cost has been incurred. A total of 200 units were produced in Job 413.

Could someone show me step-by-step how to do this thank you.
