CarryALL, Inc., makes and sells small cargo trailers to individuals and small businesses. Since its opening in 1990, it has allocated indirect costs (IDC) to its three manufacturing plants based on direct materials cost per unit. Each plant builds different models and sizes. Because of advances in automation and materi­als, Judy, the CFO, plans to use build-time per unit as the new basis. Build-time is the average number of work-hours to complete a trailer. However, she ini­tially wants to determine what the allocation would have been this year had the build-time basis been used prior to the incorporation of new technology and materials. The data shown below represents aver­age costs and times. Use this data and the bases indi­cated to determine the allocation rates and IDC

allo­cation of $1,000,000 for this year for the three bases.
