A company produced 12,000 units of a product. The prime cost was $407,000. In total, 2,200 machine hours were used to produce the product. Setup hours for the period were 1,400. The activity rates were $45 per machine hour and $110 per setup hour. What is the unit cost of the product using overhead rates, based on machine hours and setup hours?
