EXERCISE 4 Triad Electronics manufactures circuit-testing devices in a single department. Three different models are produced: Standard, Economy, and Deluxe. All three models require the same amount of pro- cessing time; the differences between the three models are in the materials used. During the month, $91,400 in conversion costs were expended. Production statistics are as follows Standard 50 units 60% 600 units 40 units 60% $45 Economy 50 units 60% 900 units 60 units 40% $25 Deluxe Beginning WIP 25 units 40% 800 units 30 units 40% $80 % completed Started.. Ending WIP ....6 % completed. Required Determine the transferred-out and ending work-in-process values using operational costing. Use job-order costing for materials and FIFO process costing for conversion costs. Assume that mate- rials are added at the beginning of the process
