(EUP; weighted average & FIFO) The Mountain Coal Company mines and pro¬ cesses coal that is sold to four power plants in Northeast Indiana. The company employs a process costing system to assign production costs to the coal it pro¬ cesses. For the third week in March 1997, the firm had a beginning Work in Process Inventory of 50,000 tons of ore that were 100 percent complete as to material and 30 percent complete as to conversion costs. During the week, an additional 200,000 tons of ore were started in process. At the end of the week, 35,000 tons remained in Work in Process Inventory and were 70 percent com¬ plete as to material and 60 percent complete as to conversion costs.

For the third week in March:

a. Compute the total units to account for.

b. Determine how many units were started and completed.

c. Determine the equivalent units of production using the weighted average method.

d. Determine the equivalent units of production using the FIFO method.
