Exercise 11-34 (Algo) Cost Allocation: Reciprocal Method (LO 11-4) University Printers has two service departments (Maintenance and Personnel) and two operating departments (Printing and Developing). Management has decided to allocate maintenance costs on the basis of machine-hours in each department and personnel costs on the basis of labor-hours worked by the employees in each. The following data appear in the company records for the current period: Required: Allocate the service department costs using the reciprocal method.

Round your final answers to the nearest whole dollar amounts.)
