Required:

For questions 1 to 9, assume that Sweeten Company uses departmental predetermined overhead rates with machine-hours as the allocation base in both departments and Job P included 20 units and Job Q included 30 units. For questions 10 to 15, assume that the company uses a plantwide predetermined overhead rate with machine-hours as the allocation base.

Compute the predetermined overhead rate for each department. (Round your answers to 2 decimal places.) Ising the predetermined overhead rates that you computed in requirement (1), compute the total manufacturing cost ssigned to Job 203. (Round your intermediate calculations and final answer to 2 decimal places.) Would you expect substantially different amounts of overhead cost to be assigned to some jobs if the company used a plantwide predetermined overhead rate based on direct labor-hours, rather than using departmental rates
