Greife Corporation's activity-based costing system has three activity cost pools--Machining, Setting Up, and Other. The company's overhead costs have already been allocated to these cost pools as follows:

Machining $ 57,408

Setting Up $ 103,554

Other $ 21,700

Costs in the Machining cost pool are assigned to products based on machine-hours (MHs) and costs in the Setting Up cost pool are assigned to products based on the number of batches. Costs in the Other cost pool are not assigned to products. The following table shows the machine-hours and number of batches associated with each of the company's two products:

MHs Batches Product K0 2,930 / 1,200

Product W9 8,110 / 780

Total 11,040 / 1,980
