Materials are entered from smelting at the beginning of the rolling process. The inventory of work in process rolling on September 1 and debits to the account during September were as follows:

Bal., 400 units, 20% complete:

Direct materials (400 x $4.8). $1,920

Conversion (400 x 20% x $2). 160

$2,080

From smelting department, 9,160 units. $44,884

Direct labor. 12,449

Factory overhead. 6,703

During October, the units in process at the beginning of the month were complete and of the 10,500 units entering the department, all were completed except 500 units that were 90% complete.
