Rick Johnstone is employed by Westin Company. Last week he worked 46 hours assembling one of the company’s products. Westin’s employees work a standard 40-hour week, and Johnstone is paid $18 per hour. Employees are paid time and a half for any hours worked in excess of the standard 40 hours. Assuming the overtime is the result of an overall spike in demand for all products allocate Johnstone’s earnings for the week between direct labour cost and manufacturing overhead cost.
