answer all of it

7. Under which of the following conditions will the first-in, first-out method of process costing produce the same cost of goods manufactured amount as the weighted-average method? (a) When the goods produced are homogenous in nature. (b) When there is no beginning inventory. (c) When there is no ending inventory. (d) When the beginning and ending inventories are each 50% complete. 8. The Wiring Department is the second stage of Flem Company's production cycle. On May 1, the beginning work in process contained 25,000 units which were 60% complete as to conversion costs. During May, 100,000 units were transferred in from the first stage of Flem's production cycle. On May 31 , the ending work in process contained 20,000 units which were 80% complete as to conversion costs. Material costs are added at the end of the process. Using the weighted-average method, the equivalent units were: 9. In order to compute equivalent units of production using the FIFO method of process costing, work for the period must be broken down into units: (a) Completed during the period and units in ending inventory. (b) Completed from beginning inventory, started and completed during the month, and units in ending inventory. (c) Started during the period and units transferred out during the period. (d) Processed during the period and units completed during the period
