Bunker makes two types of briefcases, fabric and leather. The company is currently using a traditional costing system with labor hours as the cost driver but is considering switching to an activity$-$based costing system. In preparation for the possible switch, Bunker has identified two activity pools: materials handling and setup. Pertinent data follow:

Fabric Case Leather Case

Number of labor hours $18,00012,000$

Number of material moves $765935$

Number of setups $57133$

Total estimated overhead costs are $$243,900,$ of which $$204,000$ is assigned to the materials handling pool and $$39,900$ is assigned to the setup pool.
