This question is taken from the book “Introduction to Managerial Accounting” by Brewer, Garrison, and

Job P90 was completed and sold for $2,500

1. i already computed the plantwide predetermined overhead rate at $14
2. i already computed the total manufacturing cost for Job P90 at $2,988

i need help with this question:

a. Construct an argument (supported by numerical analysis) that REFUTES the chief financial officer’s assertion.
