Henry's Kitchens makes two types of sandwich makers: Basic and Deluxe. The company expects to manufacture 70,000 units of Basic, which has a per-unit direct material cost of $10 and a per-unit direct labor cost of $60. It also expects to manufacture 30,000 units of Deluxe, which has a per-unit material cost of $15 and a per-unit direct labor cost of $40. It is estimated that Basic will use 140,000 machine hours and Deluxe will require 60,000 machine hours. Historically, the company has used the traditional overhead allocation method and applied overhead at a rate of $21 per machine hour. It was determined that there were three cost pools, and the overhead for each cost pool is shown:

Machine setups $90 000

Machine processing 4 000 000

Material requisitions 100 000

Total overhead $ 4 190 000

The cost driver for each cost pool and its expected activity is shown:

Machine setups 100 200 300

Machine hours 140,000 60,000 200,000
