Final answer:
The overhead assigned to each unit produced at H. Company is $8.17, calculated by determining the plantwide overhead rate and multiplying it by the machine hours required per unit.
Step-by-step explanation:
To calculate the overhead assigned to each unit produced at H. Company, we first need to determine the plantwide overhead rate using machine hours as the allocation base. The company expects to produce 600,000 units next year, with each unit requiring 0.75 machine hours.
The total manufacturing overhead costs are the sum of the overhead costs for Department 1 and Department 2, which is $3,107,500 + $1,520,000 = $4,627,500. The total machine hours from both departments are 250,000 MH + 175,000 MH = 425,000 MH.
To find the plantwide overhead rate, divide the total manufacturing overhead costs by the total machine hours: $4,627,500 / 425,000 MH = $10.89 per machine hour. Since each unit requires 0.75 machine hours, the overhead assigned to each unit is 0.75 MH × $10.89/MH = $8.17 per unit.
