Central Plain uses ABC to account for its chrome wheel manufacturing process. Company managers have identified four manufacturing activities that incur manufacturing overhead costs: materials handling, machine set-up, insertion of parts, and finishing. The budgeted activity costs for the upcoming year and their allocation bases are as follows:

Central Plain expects to produce 1,000 chrome wheels during the year. The wheels are expected to use 2,800 parts, require 20 set-ups, and consume 2,200 hours of finishing time.
Job 420 used 250 parts, required 3 set-ups, and consumed 130 finishing hours.
Job 510 used 475 parts, required 6 set-ups, and consumed 300 finishing hours.
