Asembling dimana ditambahin katup, piston dan komponen2 lain, kemudian di uji di dep Finishing

Diminta:
1)  Buat laporan produksi  Dept Casting dan Dep Finishing dg metode Average Cost
2) Jika masing2 Dep mempunyai rekening WIP sendiri2, buat jurnal untuk mencatat
pembebanan biaya produksi dan transfer biaya antar departemen tersebut
