Koehler (see Exercise E19-15) makes handheld calculators in two modelsbasic and professionaland wants to refine its costing system by allocating overhead using departmental rates. The estimated $721,000 of manufacturing overhead has been divided into two cost pools: Assembly Department and Packaging Department. The following data have been compiled: Assembly Department Packaging Department Total $ 456,500 $ 264,500 $ 721,000 Overhead costs Machine hours: Basic Model Professional Model Total Direct labor hours: Basic Model Professional Model Total 185,000 MHT 230,000 MHT 415,000 MHT 45,000 MHT 55,000 MHT 100,000 MHT 230,000 MHT 285,000 MHT 515,000 MHT 20,000 DLHT 105,125 DLHO 125,125 DLHO 50,000 DLHT 280,625 DLHO 330,625 DLHO 70,000 DLHO 385,750 DLHO 455,750 DLHO Compute the predetermined overhead allocation rates using machine hours as the allocation base for the Assembly Department and direct labor hours for the Packaging Department. How much overhead is allocated to the basic model? To the professional model? Round allocation rates to two decimal places and allocated costs to whole dollars
