Consider two types of karaoke machines made by SharpPitch, Inc. One machine, designed for professional use, is complex to make and is produced in many batches. The other machine, designed for home use, is simple to make and is produced in few batches. Suppose that SharpPitch needs the same number of machine-hours to make each type of karaoke machine and that Forrester allocates all overhead costs using machine-hours as the only allocation base. How, if at all, would the machines be miscosted? Briefly explain why.3. How is the cost hierarchy helpful to SharpPitch in managing its business?
