Assume that we select three representativerefrigerators (out of 333): one low-, one medium-, and onehigh-volume refrigerator. Additionally, we assume the followingactivity-base information for each of the three refrigerators:Three RepresentativeRefrigeratorsNumber ofMachine HoursNumber ofSetupsNumber ofSales OrdersNumber ofUnitsRefrigerator—Low Volume202266100Refrigerator—Medium Volume320201471,600Refrigerator—High Volume1,000152205,000Prior to conducting the study, the factory overhead allocationwas based on a single machine hour rate. The machine hour rate was$100 per hour. After conducting the activity-based costing study,assume that three activities were used to allocate the factoryoverhead. The new activity rateinformation is assumed to be asfollows:Machining ActivitySetup ActivitySales OrderProcessing ActivityActivity rate$100$150$30Complete the following table, using the single machine hour rateto determine the per-unit factory overhead for each refrigerator(Column A) and the three activity-based rates to determine theactivity-based factory overhead per unit (Column B). Finally,compute the percent change in per-unit allocation from the singleto activity-based rate methods (Column C).If required, round all per unit answers to the nearest cent.Round percents to one decimal place. For column C, use the minussign to indicate a negative or decrease.Column AColumn BColumn CProduct Volume ClassSingle RateOverhead AllocationPer UnitABCOverhead AllocationPer UnitPercent Change inAllocationLow$$%Medium$$%High$$%
