She cannot understand why this line is not more profitable given that window coverings are less complex to install for residential customers. In addition, the residential client base resides close to the company office, so travel costs are not as expensive on a per-client visit for residential customers. As a result, she has decided to take a closer look at the overhead costs assigned to the two product lines to determine whether a more accurate product costing model can be developed. Following are the three activity cost pools and related information she developed: Activity Cost Pools Estimated Overhead Cost Drivers Scheduling and travel $ 87,920 Hours of travel Set-up time 78,000 Number of set-ups Supervision 51,080 Direct labour cost Use of Cost Drivers per Product Commercial Residential Scheduling and travel 930 640 Set-up time 400 200
