(b) Using your calculations from part (a), calculate the under-applied or over-applied overhead based on October€™s portion of the annual estimate.
(c) Assume that Intronin chooses to use machine hours to apply all overhead costs to products. What is the predetermined overhead rate? How much overhead would be assigned to each unit of Product X and Product Y?
(d) Using your calculation from part (c), calculate the under-applied or over-applied overhead based on October€™s portion of the annual estimate.
(e) The manager of Product X argues that direct labor hours should be used to apply overhead, while the manager of Product Y argues that machine hours should be used. Why are they arguing?
