Transferred$-$in costs, FIFO method $($continuation of $18-43).$ Refer to the information in Problem $18-43.$ Suppose Spelling Sports uses the FIFO method instead of the weighted$-$average method. Assume that all other information, including the cost of beginning work in process, is unchanged. $1.$ Do Problem $18-43$ using the FIFO process$-$costing method. $2.$ If you did Problem $18-43,$ explain any difference between the cost of work completed and transferred out and the cost of ending work in process in the stitching department under the weighted$-$average method and the FIFO method.
