The Zaf Radiator Company uses a normal-costing system with a single manufacturing overhead cost pool and machine hours as the cost allocation base. The following data for 2017:

Budgeted manufacturing overhead cost $4,800,000

Overhead allocation base-machine hours

Budgeted machine-hours 80,000

Manufacturing overhead costs incurred $4,900,000

Actual machine-hours 75,000

Machine-hour data and the ending balances(before proration of under or over allocated overhead) are as follows:

Costs of goods sold: actual machine hours-60,000 & end of year balance for 2014 $8,000,000

Finished goods control: actual machine hours- 11,000 & end of year balance 1,250,000

Work in process control: actual machine hours 4,000 & 750,000 for end of year balance for 2014
