17-19 Weighted-average method, equivalent units. The assembly division of Fenton Watches, Inc., uses the weighted-average method of process costing. Consider the following data for the month of May 2014: Physical Units (Watches) Direct Materials Conversion Costs Beginning work in process (May 1)a Started in May 2014 Completed during May 2014 Ending work in process (May 31)b Total costs added during May 2014 80 500 460 120 $ 493,360 $3,220,000 $ 91,040 $1,392,000 aDegree of completion: direct materials, 90%; conversion costs, 40%. bDegree of completion: direct materials, 60%; conversion costs, 30%. Compute equivalent units for direct materials and conversion costs. Show physical units in the first column of your schedule.

17-20 Weighted-average method, assigning costs (continuation of 17-19). For the data in Exercise 17-19, summarize the total costs to account for, calculate the cost per equivalent unit for direct materials and conversion costs, and assign costs to the units completed (and transferred out) and units in ending work in process.
