Required: 1. Enter the balance as of September 1 in a four-column account for Work in Process-Rolling. Record the debits and the credits in the account for September. Construct a cost of production report and present computations for determining (a) equivalent units of production for materials and conversion, (b) costs per equivalent unit, (c) cost of goods finished, differentiating between units started in the prior period and units started and finished in September, and (d) work in process inventory. If an amount box does not require an entry, leave it blank. ACCOUNT Work in Process-Rolling Department ACCOUNT NO. BALANCE DATE ITEM POST. REF.
