Show me the steps to solve Brite Ideas, Incorporated, mass$-$produces reading lamps. Materials used in constructing the body of the lamp are added at the start of

the process, while the materials used in wiring the lamps are added at the halfway point. All labor and overhead are added evenly

throughout the manufacturing process. Brite Ideas uses process costing and had the following unit production information available for

the months of June and July:

In June, the lamps in beginning work in process were approximately $90$ percent complete, while those in ending work in process were

only $30$ percent complete. In July, the units remaining in ending work in process were $80$ percent complete. All lamps in ending work

in process each month are finished in the following month.

Required

a$.$ For the month of June, calculate the equivalent units of production for the three major cost categories$-$body materials, wiring

materials, and labor and overhead.

b$.$ For the month of July, calculate the equivalent units of production for the three major cost categories$-$body materials, wiring

materials, and labor and overhead.

Answer is complete but not entirely correct.
