Problem $6-36($Algo$)$ Weighted$-$Average Method $[$LO $6-2,6-4]$

McElroy, Incorporated produces a single model of a popular cell phone in large quantities. A single cell phone moves through two departments, assembly and testing. The manufacturing costs in the assembly department during March follow:

Direct materials $ $124,000$

Conversion costs $99,750$

$ $223,750$

The assembly department has no beginning Work$-$in$-$Process Inventory. During the month, it started $20,000$ cell phones, but only $15,000$ were fully completed and transferred to the testing department. All parts had been made and placed in the remaining $5,000$ cell phones, but only $50\%$ of the conversion had been completed. The company uses the weighted$-$average method of process costing to accumulate product costs.

Required:

$1.$ Compute the equivalent units and costs per equivalent unit for March in the assembly department.

$2.$ Compute the cost of units completed and transferred to the testing department.

$3.$ Compute the cost of the ending Work$-$in$-$Process.
